ABSTRACT
Objective To study the imaging features and adequate interventional therapy of the diffuse type hepatic cellular carcinoma(HCC).Methods Fourteen patients with the diffuse type HCC underwent hepatic angiography and the adequate interventional therapy by TAI or TAE according to imaging appearances,blood supply and function of liver.Results ①Imaging appearances:the most common appearances of fourteen patients with the diffuse type HCC on DSA and CT included:tumor blood vessel was extensive and increased,tumor stain was extensive in left and right liver leaf(such as grain,small spot ,nodule shadows or low density area),liver enlarged obviously with liver cirrhosis,portal vein tumor thrombus,arteriopotal shunt and widespreadly scattered iodized oil,et al.②Therapeutic effect:the mean survival time of fourteen patients was 3 months,the longest survival period was 10 months and the shortest one was olny 15 days.Conclusion ①The specific appearances of the diffuse type HCC are diffuse small spot-like,frosted glass-like,double orbit-like and big liver-like.②The interventional therapeutic effect and prognosis of the diffuse type HCC are the worst than that of other type primary hepatic carcinoma.Selecting adequate interventional therapeutical plan can obviously prolong survival time of the patient.
ABSTRACT
Objective To study the procedure of imaging examination for the patients with colon cancer.Methods The comparative study on ultrosonograph, pneumobarium double contrast examination, colonscopy and CT in 82 cases with colon carcinoma comfired by operation and pathalogy were carried out.Results The detective rate of colon cancer was 90.1%,89.5%,53.8% and 53.3% by pneumobarium double contrast examination,colonscopy ultrosonography and CT respectively.The detective rate of metastasis in liver was 100% by ultrosonograph and CT.Conclusion Pneumobarium double contrast examination and colonoscopy are the main methods for diagnosis of colon cancer. Ultrosonography and CT are the important methods in evaluating the stage of colon carcinoma before operation.
ABSTRACT
Objective To study imaging findings of Sturge-Weber syndrome. Methods The clinical manifestations and imaging findings of 11 cases suffered from Sturge-Weber syndrome were analysed. 10 cases had facial vascular nerves angioma in the trigeminal nerve distribation. Routine CT examination was performed in all 11 cases, 2 cases had head radiography and 8 cases had MRI, 5 cases had enhanced CT and 3 cases had enhanced MRI.Results Imaging finding included:on the affected hemisphere, cortical calcifications (n=11), brain atrophy (n=9), the interfaces between gray matter and white matter blured, dilated subependymal veins,enlargeel choroids plexus (n=7) and increasing thickness of cranial diploe (n=8). The choroids plexus of lateral ventricle was prominent enhanced in 5 cases. Enhancement of cortical areas and vessels on the surface of brain were noted in 6 cases. Conclusion Head radiography has finite effects in the diagnosis of Sturge-Weber syndrome, MRI combined with CT plays an important role in the diagnosis of this syndrome.
ABSTRACT
Objective To discuss the imaging representations and its clinical significance of acute indigitation in infants.Methods The imaging representations including CT,ultrasonography stand abdominal plain film and gas clysters of indigitation comfirmed by operation in 58 infants were analysed.Results (1)Of 58 cases,33 were ileum-colon and ileum-caecal type,25 were ileum-ileum-colon,ilem-cecal-colon and ileum-colon-colon type;(2)The main imaging representations were as following:gas decreased in colon of small intestine (12 cases),inflation in intestine and incomplete ileus (18 cases),ileus of small intestine(17 cases),no abnormity on stand abdominal plain film (8 cases).Gas clyster showed the "goblet sign" and masses (28 cases).The sign of targed rings was seen on ultrasonography(3 cases).The layered homocentric round tumors showed by CT (1 case).Conclusion The imaging representations of acute indigitation in infants are typical,which are significant for the diagnosis.
ABSTRACT
Objective To discuss the imaging diagnostic value using seven division for dystopic thymomas in mediastinum. Methods 11 cases of dystopic thymomas proved by biopsy and histopathology were analyzed based on chest radiography, computed tomography (CT) and magnetic resonance imaging (MRI) .Results According to nine division, 3 cases located in left mid-middle and mid-inferior mediastinum, 4 cases in right mid-middle and mid-inferior mediastinum, 4 cases in right ante-middle and ante-inferior mediastinum.While according to seven division,all cases (11) located in ante-inferior mediastinum. Conclusion Seven division of mediastinum is of great value in diagnosing dystopic thymomas and in guiding clinical management.
ABSTRACT
Objective To explore the clinical value of imaging examinations of medullary sponge kidney with the literature reviewed.Methods The features of X-ray plain film (1 case),IVP (2 cases),B-mode US(3 cases) and CT images (9 cases) of medullary sponge kidney (MSK) in 11 cases were analysed retrospectively.Results X-ray plain film showed a cluster of round and oval high density images in renal papillae and renal medulla in one case one kidney.Collecting tubes were showed as like line,brush and sac like dilatation on IVP in 2 cases 3 kidneys.B-mode US revealed a cluster of high echo spots scattered in renal medulla in 3 cases 5 kidneys and sac like dilatation of collecting tubes in 2 cases 3 kidneys.CT images showed the stones of spongiform kidney scattered alone renal medulla in 9 cases 16 kidneys,while the stones covered by contrast media on enhanced CT images in 3 cases 5 kidneys,and enhanced stripes of high density projected from renal papillae to renal medulla.Conclusion X-ray plain film,IVP,B-made US and CT all can be used in diagnosing spongiform kidney.Plain film and IVP are yet the first selected methods and IVP is specific and direct in showing collecting tubes dilatation.B-mode US especially CT have a high showing rate of stone in spongiform kidney and can be helpful to evaluate the collecting tube dilatation.
ABSTRACT
Objective To improve diagnostic ability of mycoplasmal pneumonia in children.Methods The clinical data and X-ray findings of 563 cases with mycoplasmal pneumonia who hospitalized during 1999～2000 were retrospectively analyzed.Results Obvious abnormalities were seen on the chest films,which were in sharp contrast with the mild clinical respiratory symptoms.Erythromycin produced very effective results.Chest X-ray findings of mycoplasmal pneumonia were as follows:Pulmonary interstitial infiltration(417 cases,74%),parenchymatous infiltration(104 cases,18%),and mixed pattern (42 cases,8%),of them,pleurisy(63 cases,11%)and the hila lymph node enlargement (105 cases,19%).Conclusion The X-ray findings of mycoplasmal pneumonia are variant,a correct diagnosis can be made if one combines X-ray findings closely with laboratory results.
