Harmonic ultrasonography for the detection of microlithiasis in the gallbladder

PURPOSE: To validate the use of harmonic ultrasonography (US) in the detection of gallbladder microlithiasis. METHODS: From November 30, 2012, to January 18, 2014, fundamental US (FUS) and harmonic US with a high background noise (HUS-N) were performed for evaluation of gallbladder during the routine abdomen US. During the US, a dot-like stone (or stones) with Brownian motion was regarded as a positive finding of microlithiasis. Fifty-five patients with microlithiasis in the gallbladder detected on US were enrolled as the subjects of a retrospective review. With respect to the obtained images, two abdominal radiologists independently scored the conspicuity of gallbladder microlithiasis on FUS and HUS-N by using a 4-grade scale. The statistical analysis employed a kappa test and a Wilcoxon rank-sum test. RESULTS: For FUS, the conspicuity grades of gallbladder microlithiasis were G1 in 25 and 37, G2 in 21 and 9, G3 in 6 and 6, G4 in 3 and 3 patients, while HUS-N showed G1 in 0 and 0, G2 in 3 and 2, G3 in 12 and 15, and G4 in 40 and 38 patients, respectively, by each of the two radiologists. The kappa value was 0.633 for FUS between the two radiologists and 0.708 for HUS-N. HUS-N showed better conspicuity of gallbladder microlithiasis than FUS with significant P-values of less than 0.001 and 0.001 for the two radiologists, respectively. CONCLUSION: Compared with FUS, HUS-N enables better detection of microlithiasis in the gallbladder.

Korea's Contribution to Radiological Research Included in Science Citation Index Expanded, 1986-2010

OBJECTIVE: To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. MATERIALS AND METHODS: The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing "Korea" and "radiol" in the address section and selecting the subject area of "Radiology, Nuclear Medicine, and Medical Imaging" with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. RESULTS: Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n = 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). CONCLUSION: The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

Prognostic significance of computed tomography defined ascites in advanced gastric cancer / 대한외과학회지

PURPOSE: The aim of this study was to investigate the clinicopathologic features and prognosis in patients with computed tomography (CT) findings of ascites, with a focus on the correlation with peritoneal carcinomatosis. METHODS: This study included a total of 157 patients who underwent surgery for advanced gastric cancer from 2003 to 2008 at the Department of Surgery, Hallym University Kangdong Sacred Heart Hospital, Seoul, Korea, which were analyzed retrospectively. RESULTS: Fourteen patients (8.9%) presented ascites on their CT scan. Among them, 10 patients had peritoneal carcinomatosis, and showed significant difference with CT ascites positive group in the incidence of peritoneal carcinomatosis. The presence of CT ascites was significantly correlated with pathologic T stage, tumor size, histologic type, CT T and N stages, CT peritoneal nodularity and curability of surgery, statistically. The prognosis of CT ascites positive group was much poorer in the total advanced gastric cancer patients (P < 0.001), as well as in patients with pathologic T4 (P = 0.002). Also in patients without peritoneal carcinomatosis, CT ascites positive subgroup tended to have a worse prognosis than CT ascites negative subgroup (P = 0.086). Tumor size, CT T and N stages and the presence of CT peritoneal nodularity and ascites influenced the prognosis significantly; among which, if a tumor size larger than 5 cm, CT T4 stage and the presence of CT ascites were identified as independent prognostic factors. CONCLUSION: The presence of ascites was closely associated with peritoneal metastasis, and was the most significant independent prognostic factor in advanced gastric cancer in the present study.

Calcified Carcinoma of the Gallbladder with Calcified Nodal Metastasis Presenting as a Porcelain Gallbladder: A Case Report / Journal of the Korean Cancer Association, 대한암학회지

Porcelain gallbladder is regarded as a risk factor of gallbladder cancer. A porcelain gallbladder with calcified regional lymph nodes was found using computed tomography (CT) and magnetic resonance imaging (MRI) in a 43-year-old man who presented with nausea, vomiting, and abdominal pain. His cholecystectomy specimen showed diffuse wall thickening and contained small gallstones. Histological examination revealed diffuse infiltrative adenocarcinoma with extensive intratumoral calcification (calcified carcinoma). The majority of the calcified material was located within or replaced the tumor glands, and was not found in the stroma. A lymph node was totally replaced with a calcified metastatic adenocarcinoma. To the best of our knowledge, only one case of calcified lymph node metastasis from a calcified carcinoma of the gallbladder has been previously reported in the literature. We herein add a case of calcified carcinoma of the gallbladder with calcified lymph node metastasis, presenting as a porcelain gallbladder on CT and MRI.

The Efficacy of Unenhanced MR Imaging for the Diagnosis of Acute Appendicitis: A Performance Comparison Versus Abdominal Ultrasonography

PURPOSE: To evaluate the efficacy of unenhanced MR imaging compared to the diagnostic accuracy, advantage, and limitations of abdominal ultrasonography in the diagnosis of acute appendicitis. MATERIALS AND METHODS: The study included 40 patients suspected of having acute appendicitis and who were subjected to an unenhanced MR image, as well as an abdominal ultrasonography. A T1 FLASH in an axial image, a chemical shift-selective fat suppressed T2 HASTE in an axial image, as well as a T2 HASTE in an axial and coronal image were obtained as unenhanced MR images. The diagnosis was established based on a surgical or clinical follow-up of the unenhanced MR results, which were then statistically compared to the ultrasonographic results. RESULTS: The surgical or clinical follow-up results revealed that 25 patients were positively diagnosed with appendicitis. Of these, 7 patients had symptoms of acute appendicitis with no pathologic diagnoses, whereas the 8 remaining patients were diagnosed with another condition. The sensitivity and accuracy of the unenhanced MR imaging was 92% and 90%, compared to ultrasonography which was 68% and 72.5% accurate, respectively. The differences in sensitivity and accuracy between the two methods were found to be statistically significant (p < .05, chi-square test). Based on these results, unenhanced MR imaging was superior to sonography for the diagnosis of appendicitis. CONCLUSION: Unenhanced MR imaging may be a useful modality for the diagnosis of acute appendicitis, especially for suboptimal or nondiagnostic sonographies, as well as patients that are particularly sensitive to radiation exposure.

Publication Rates for Abstracts Presented by Korean Investigators at Major Radiology Meetings

OBJECTIVE: To determine the publication rate of abstracts presented by Korean investigators at national and international radiological meetings, and to identify predictive factors of publication. MATERIALS AND METHODS: Abstracts presented at the annual meetings of the Korean Radiological Society (KRS), and abstracts presented by Korean investigators at the annual meetings of the Radiological Society of North America (RSNA) and European Congress of Radiology (ECR) from 2001 to 2002 were searched for subsequent publication, using PubMed and the Korean Medical Database. The following variables were evaluated. 1) The overall publication rate; 2) the publication rates according to the radiological subspecialty, presentation type (oral or poster), sample size ( 50), study design (prospective or retrospective), statistical analysis (present or absent), and study outcome (positive or negative); 3) the time to publication; 4) the journal where the study was published; 5) consistency between the abstract and the final publication. RESULTS: Of 1,097 abstracts, 301 (27.4%) were subsequently published, at an average of 15.8 +/- 13.8 months after presentation in 48 journals. The publication rates for studies presented at the RSNA (35.4%) and ECR (50.5%) conferences were significantly higher than that for the KRS conference (23.6%, p < 0.05). Vascular/interventional radiology studies had the highest publication rate (33.1%), whereas musculoskeletal radiology studies had the lowest publication rate (17.1%). Other factors associated with subsequent publication were prospective design, use of statistical testing, and a positive study outcome. CONCLUSION: The publication rate is significantly lower for the KRS (23.6%) meeting abstracts as compared to those of the RSNA (35.4%) and ECR (50.5%). Prospective design, use of statistical testing, and positive study outcome have a statistically significant effect on the publication rate.

CT, MR, and Angiography Findings of a Solitary Fibrous Tumor of the Larynx: a Case Report

This report details the CT, MR, and angiography findings of a solitary fibrous tumor involving the larynx of a 34-year-old man. A precontrast CT scan revealed a well-defined isodense mass in the submucosal region of the supraglottic larynx. The tumor appeared as a mixed intensity lesion on the T1- and T2-weighted MR images. A T2-weighted MR image showed a central, round, and low signal intensity area within the mass. For both the CT and MR images, the mass demonstrated heterogeneous enhancement following the administration of contrast material. The angiography showed a hypervascular tumor with heterogeneous persistent staining.

Diagnostic Usefulness of CT Attenuation Coefficients of Urine after Enteral Administration of Iodinated Water (Iohexol) in Neonates with NEC

PURPOSE: We wanted to evaluate the clinical efficacy of an increased computed tomography attenuation coefficient (CTAC) of urine after the oral administration of iohexol in neonates who are suspected of suffering with neonatal necrotizing enterocolitis (NEC). MATERIALS AND METHODS: During a recent 1 year-period, seventeen neonates were admitted for suspected NEC, and they were divided into the suspected and definite groups based on their clinical signs and radiographic findings; we also included ten normal neonates as the control group. Diluted iohexol was administered and the CTACs of collected urine samples at 8-12 hour intervals were measured. Comparative analysis of the three groups was done and statistical significance was determined by the Scheffe test. RESULTS: Among 17 neonates, there were 13 neonates in the suspect group and 4 neonates in the definite group. The mean CTACs of urine in each group were 2711 HU (control group), 3411 HU (suspected group), and 7625 HU (definite group), respectively. There was a significant difference between the mean CTAC of the definite group and that of the control or suspected groups (Scheffe t >2.65). However, no statistically significant difference was seen between the suspected and control groups (Scheffe t=1.14). CONCLUSION: Although measurements of the CTAC of urine showed no significant diagnostic efficacy in the suspected group, the CTAC of urine, which reflects the correlated degree of bowel mucosal injury, can be a useful aid for determining the severity and progression of NEC.

The Detection of Gallstones on MR Cholangiopancreatography: Comparison between the Single-Shot Turbo Spin-Echo Pulse Sequence and the Three-Dimensional Turbo Spin-Echo Pulse Sequence with the SENSE Technique

PURPOSE: We wanted to evaluate the detectability of gallstones on magnetic resonance cholangiopancreatography (MRCP) and to compare the accuracy between the single-shot turbo spin-echo (SSTSE) sequence and the three-dimensional turbo spin-echo (3DTSE) sequence with the sensitivity encoding (SENSE) technique. MATERIALS AND METHODS: A total of 141 patients who had undergone MRCP for a year period since August, 2003 were involved in the study. The source axial-SSTSE, coronal-SSTSE, source coronal-3D TSE and maximum intensity projection (MIP)-3DTSE images were obtained. Based on the operative findings and the findings of the ultrasound and CT examinations, the results of the reading by two investigators for the presence of gallstones were compared and analyzed. RESULTS: Among 141 patients, 135 patients were included in the study. 69 cases (51%) were found to have gallstones. In terms of detection of gallstones, the accuracy was 85%. The reading by one investigator greatly accorded with that of the other investigator (κ=0.94). As a result of comparing the four kinds of images obtained with the different techniques, it was found that gallstones were seen best on the source axial-SSTSE and source coronal-3DTSE images; the coronal-SSTSE image was the next best image and the MIP-3DTSE image followed (p<0.01). CONCLUSION: The detectability of gallstones on MRCP was relatively excellent and the source axial-SSTSE and source coronal-3DTSE imagings should be included for the detection of gallstones.

Primary Carcinoid Tumor of the Testis: Case Report

Primary testicular carcinoid tumors are extremely rare and account for less than 1% of all testicular tumors. We recently experienced a case of primary carcinoid tumor of the testis in a 50-year-old man who presented with scrotal swelling. The ultrasonographic findings were evaluated and compared with those of previous reports.

Intraparotid Lymphadenopathy: Ultrasonographic and CT Findings

PURPOSE: The purpose of this study was to evaluate the ultrasonographic and CT findings of various diseases that affect the intraparotid lymph node. MATERIALS AND METHODS: The subjects were 32 patients having various diseases involving the intraparotid lymph node. The final confirmed diagnoses were nonspecified benign inflammatory lymphadenopathy (n=20), metastasis (n=5), tuberculous lymphadenitis (n=4), and lymphoma (n=3). For the nonspecified benign inflammatory lymphadenopathy, there were multiple lesions in five patients and bilateral lesions in two patients, and a total of 26 lesions were included in this study. The pathologic proof of the diagnosis was made for 4 of 26 lesions, and by ultrasound follow-up on 22 of 26 lesions. All the patients underwent ultrasound. Color Doppler imaging was also performed in 19 patients and contrast-enhanced CT was also performed in 8 patients. All cases with metastasis, tuberculous lymphadenitis and lymphoma were pathologically confirmed and these patients were all examined with contrast-enhanced CT. RESULTS: For the nonspecified benign inflammatory lymphadenopathy, all the lesions were seen at the superficial lobe. All twenty six lesions were observed as well-defined ovoid or round hypoechoic nodules with posterior sonic enhancement on ultrasonography. A central echogenic hilum was seen in 12 of 26 inflammatory lymphadenopathies (46%), and a central hilar vascularity was noted in 13 of 19 inflammatory lymphadenopathies (68%) on color Doppler imaging. Contrast-enhanced CT showed well-defined nodules with homogeneous enhancement in most lesions. In 3 lesions, a central low density hilum was seen within a lymph node. In 12 cases with metastasis, tuberculous lymphadenitis and lymphoma, there were multiple lesions in 6 cases. CT revealed intraparotid masses with or without central necrosis and the associated multiple lymph node enlargements in the ipsilateral neck region, and their appearances were similar to that of parotid mass. CONCLUSION: Nonspecified benign inflammatory lymphadenopathy involving intraparotid lymph nodes often demonstrated characteristic ultrasonographic findings, including a central echogenic hilum on gray scale US and central hypervascularity on color Doppler ultrasonography. In the metastasic lesions, the tuberculous lymphadenitis and the lymphomas, the multiplicity of lesions and the associated enlarged lymph nodes in the ipsilateral neck region could be helpful in the differential diagnosis.

Trends of Bacterial Zoonoses in Humans in Korea

Out of 60 national communicable diseases in Korea, 23 are zoonoses, diseases transmissible from animals to humans. Among the bacterial zoonoses, plague, brucellosis, anthrax, Q fever, tularemia, glanders, and melioidosis are categorized as a high-level threat of bioterrorism and biowarfare in the world. In this paper, the trends of notifiable bacterial zoonoses recently occurring or recurring in Korea and other potential pathogens for bioterrorism or biowarfare are reviewed. Notifiable bacterial zoonoses recently occurring in Korea are enterohemorrhagic Escherichia coli (EHEC) infection, tetanus, tuberculosis, scrub typhus, leptospirosis, brucellosis, and anthrax. Other bacterial diseases recently emerging are tularemia, ehrlichiosis, and Q fever. However, no human case of plague, glanders, and melioidosis has been reported yet.

Differentiation of Tuberculous Enteritis and Crohn's Disease with Barium Study Using Bayes Theory

PURPOSE: To differentiate tuberculous enteritis and Crohn's disease with barium study using Bayes theory. MATERIALS AND METHODS: The study group consisted of 34 patients with tuberculous enteritis (age range 16-86 years, mean age 43.3 years, M:F=19:15) and 36 patients with Crohn's disease (age range 19-78 years, mean age 35.2 years, M:F=18:18). These diagnoses were confirmed by therapeutic tests (tuberculous enteritis: 15, Crohn's disease:16) or histopathological examinations (tuberculous enteritis: 19, Crohn's disease: 20) conducted from January 1993 to May 2003. Three radiologists (two abdominal specialists and one trainee) analyzed each radiological finding of tuberculous enteritis and Crohn's disease by means of a barium enema and/or small bowel series. We used Fisher's exact test to verify the statistical significance of each radiological finding and p-values less than 0.05 were considered to be significant. We calculated the likelihood ratio (LR) of tuberculous enteritis versus Crohn's disease for each finding by employing Bayes theory. RESULTS: The radiological findings associated with a high likelihood ratio for tuberculous enteritis were the involvement of the cecum (LR=2.65) and ascending colon (LR=1.99), rigid narrowing (LR=1.94), shortening of the bowel (LR=1.99), haustral loss (LR=1.97) and sacculation (LR=3.88). The radiological findings associated with a high LR for Crohn's disease (low LR for tuberculous enteritis) were age between 20 and 29 years (LR=0.53), the involvement of the jejunum (LR=0.12), terminal ileum (LR=0.19), sigmoid colon (LR=0.30) or rectum (LR=0.17), and the presence of skip lesions (LR=0.19) or strictures (LR=0.21). With these LRs, the probability of the subject having tuberculous enteritis versus Crohn's disease could be calculated using Bayes theory. CONCLUSION: The analysis of a barium study using Bayes theory could provide an objective, easy and fast method of differentiating tuberculous enteritis and Crohn's disease.

Mucopolysaccharidosis: Abnormal Findings on Abdomen and Chest Excluding Musculoskeletal System

PURPOSE: Mucopolysaccharidosis (MPS) is a lysosomal storage disease that causes tissue distortion and dysfunction due to the infiltration of mucopolysaccharide in connective tissue. The purpose of this study was to evaluate the characteristic findings of abdominal CT and plain chest radiography in patients with MPS. MATERIALS AND METHODS: Sixty-two children with MPS diagnosed by urine analysis were involved in this study; 24 of these underwent abdominal CT and the findings were reviewed by two radiologists, who reached a consensus. Organomegaly was classified as severe, moderate or mild. On chest PA radiographs of 42 of the children, the transverse diameter of the trachea was measured and compared with that of 42 normal controls. Student's t test was used for statistical analysis. RESUTLS: At abdominal CT, hepatomegaly was observed in 22 patients (92%; 2 severe, 15 moderate and 5 mild); and splenomegaly was present in 18 (75%; 2 severe, 4 moderate and 12 mild). Among eight patients (33%) with pancreatic enlargement, one had a severly enlarged pancreas, while in the remaining seven, enlargement was mild. Also present were inguinal hernia (n=15), umbilical hernia (n=12), undulation with thickening of the diaphragmatic crura (n=10), abnormalities related to the male genitalia (n=5) and vascular anomaly (n=3). In MPS patients, the mid-point diameter of the trachea (range, 5.6-9 mm; mean, 6.9 mm) was significantly less than in normal controls (range, 8-14 mm; mean, 10.8 mm) (p<0.001). CONCLUSION: An awareness of the characteristic abnormalities observed at abdominal CT and chest PA radiography can lead to a better understanding of MPS in children.

MR Cholangiopancreatography: Comparison Between Single-Shot Turbo Spin-Echo Pulse Sequence and Three-Dimensional Turbo Spin-Echo Pulse Sequence with SENSE Technique

PURPOSE: To evaluate the relative image qualities obtained at magnetic resonance cholangiopancreatography (MRCP) turbo spin-echo (SSTSE) sequence and the three-dimensional turbo spin-echo (3D TSE) sequence with the sensitivity encoding (SENSE) technique. MATERIALS AND METHODS: Forty patients with suspected hepatic and extrahepatic diseases underwent MRCP using the SSTSE sequence and the 3D TSE sequence with the SENSE technique. Three radiologists scored and compared the quality of images of anatomic structures in the hepatopancreatic biliary system, and then directly compared the quality of the images obtained using the two sequences in each set of cases. RESULTS: For visualization of the intrahepatic bile duct, the cystic duct, the common bile duct, and the pancreatic duct, MRCP images obtained using the 3D TSE sequence with the SENSE technique were better than those obtained using the SSTSE sequence, though for the intrahepatic bile duct and common bile duct only, were these differences statistically significant (p<0.05). Quality was best for images of the common bile duct (87.5% for SSTSE and 97.5 % for 3D TSE with the SENSE technique). For the pancreatic and cystic duct, however, 52.5% and 10% of SSTSE images, respectively, and 57.5% and 32.5% of 3D TSE images, respectively, provided optimal image quality. In direct comparison, 3D TSE images obtained using the SENSE technique were better in 27 cases (67.5%), both images were equivocal in five cases (12.5%), and SSTSE images were better in eight cases (20%). These differences were statistically significant (p<0.05). CONCLUSION: For the visualization of anatomic structures in the hepatopancreatic biliary system, the 3D TSE sequence with the SENSE technique was better than the SSTSE sequence. For evaluation of the pancreatic and cystic duct, however, both techniques have their limitations and require further development.

Oblique Coronal MRI in the Evaluation of Bony Stenosis of the Cervical Foramina: Objectiveness and Correlation with Radiograph

PURPOSE: To determine the utility of oblique coronal MR (OMR) imaging in the evaluation of bony foraminal narrowing of the cervical spine by comparison of its findings with those of combined axial and sagittal MR (CMR) imaging and correlation with the findings of oblique radiography. MATERIALS AND METHODS: One hundred and eight cervical neural foramina in 18 patients formed the basis of this study. Three radiologists working in a blind fashion independently graded the degree of bony narrowing of the foramina seen on OMR and CMR images and on oblique radiographs (0=none, 1=stenosis below 25% of AP dimension, 2=stenosis exceeding 25% of AP dimension). Inter-observer variance was measured for each modality, and for each of these and for each foramen, consensus was reached as to whether of CMR or OMR showed better correlation with radiographs. RESULTS: Inter-observer variance in OMR was less (kappa=0.88) than in CMR (kappa=0.41). Correlation between the findings of OMR and radiography was also better (kappa=0.63) than between those of CMR and radiography (kappa=0.41). CONCLUSION: OMR can be a useful supplement in evaluating foraminal stenosis, especially when oblique radiographs and CMR images show discrepancies.

Characteristics of Adult-Onset Choledochal Cyst

PURPOSE: Choledochal cyst is a rare disease associated with an anomalous junction of the pancreaticobiliary ductal system (AJPBDS). We intended to demonstrate the characteristics of adult-onset choledochal cyst retrospectively. METHODS: ERCP findings of nineteen adult cases of choledochal cyst were compared with those of nine normal persons, in respect to the length and diameter of the common channel, and the angle of the pancreaticobiliary ductal junction. RESULTS: Patients of adult-onset choledochal cyst displayed a long, ectatic common channel and a larger angle of the pancreaticobiliary junction (p<0.05). All patients except one had AJPBDS. Thirteen patients were classified as Todani type Ia, one as type Ic and five as type IVa. Fourteen patients were classified as choledochopancreatic (C-P) type, two as pancreaticocholedochal (P-C) type, and three were unclassified by Kimura's classification. Sixteen patients were compatible with cystic type and three with cylindrical type by Okada's classification. Among the three cylindrical type patients two of them were classified as P-C type and one as C-P type. Histologically cystic type patients showed mild glandular or fibrotic patterns, however cylindrical type patients tended to show the severe glandular pattern. CONCLUSION: Adult-onset choledochal cyst was closely related with AJPBDS, although the reflux of pancreatic juice due to AJPBDS would not be the only cause to determine the morphology of adult-onset choledochal cyst. The meaning of this tendency toward a severe glandular pattern in cylindrical type patients requires elucidation.

Sarcomatoid Carcinoma of the Stomach: Report of Three Cases

Sarcomatoid carcinoma is a rare neoplasm of epithelial origin but consists partly of variable differentiated tumor cells of mesenchymal origin. Accurate diagnosis, including differentiation from adenocarcinoma or gastrointestinal stromal tumor, is difficult. We experienced three cases of sarcomatoid carcinoma of the stomach, and describe the radiological and pathologic findings. One case involved a polypoid mass in the antrum, another a mass with a large ulcer mimicking a Bormann type-II adenocarcinoma in the body, while in the third case, an intraluminal bulky mass arising from the cardia of the stomach was present. This was not differentiated from cancer or stromal tumor.
