Clinical Diagnosis and Value Analysis of Multilayer Spiral CT scan in early Pancreatic Cancer in retired athletic patients

An intriguing result of esophageal malignant growth resection is pancreatic disease. This study aimed to explore the demonstrative worth of multi-facet twisting processed tomography (MSCT) in malignant pancreatic growth to work on clinical comprehension, assess a fruitful, helpful, and painless indicative methodology, and make the basis for treatment. Pancreatic disease (PC) is the deadliest harm on the planet, with a five-year endurance pace of just 5%. Although absolute careful resection is the main corrective treatment for pancreatic disease, just around 20% of recently analyzed athletic patients get their pancreas eliminated. Retired athletic patients with harmful pancreatic development at this point have advanced sickness when they are dissected, inferable from the shortfall of early aftereffects and the inclination of pancreatic adenocarcinoma to go after connecting structures or metastasize at a starting stage. In this way, there is a high demise rate. Early recognizable proof of PC is urgent for further developing retired athletic patient endurance rates. PC is breaking down using handled tomography (CT) as well as alluring resonation imaging (MRI) with appealing resonation cholangiopancreatography (MRCP), or endoscopic ultrasound for biopsy or fine-needle want (EUS). In spite of the fact that multi-identifier line registered tomography assumes a significant part in the determination of PC, MRI with MRCP takes into consideration a more thorough examination of the morphological adjustments in the pancreas parenchyma and pancreatic channel, taking into account prior recognition of malignancies. In specific situations where CT and EUS are not absolutely demonstrative, positron discharge tomography procedures could assist with the finding. (AU)

Echocardiographic evaluation of supracardiac anomalous pulmonary venous connection in children: comparison with multilayer spiral CT.

Objective To explore the clinical value of transthoracic echocardiography (TTE) in the differentiation of Supracardiac Anomalous Pulmonary Venous Connection (SAPVC) in children. Materials and methods A total of 118 children with concurrent TTE and CT databases of cases diagnosed with SAPVCs were included. We analyzed the consistency between the two for the ability to diagnose the classification of SAPVC, drainage sites, ectopic pulmonary veins and the segments of superior vena cava (SVC). Results The consistency between TTE and CT in diagnosing the existence of SAPVC and the classification were 88.1% (95% CI: 80.9-93.4%) and 91.0% (95% CI: 84.1-95.6%), respectively. The error rate of partial type diagnosed by TTE was significantly higher than that of total and mixed type (20.5% vs. 2.8%, P = 0.003). The consistency between TTE and CT to determine drainage sites was 91.9% (95% CI: 85.2-96.2%). TTE had a significantly higher error rate in determining pulmonary vein drainage to the SVC than in those draining into the left innominate vein (17.5 vs. 2.5%, P = 0.007). The consistency of TTE and CT in judging the number of veins was 87.4% (95% CI: 79.7-92.9%). The error rate in determining the presence of 2 and 5 ectopic pulmonary veins was significantly higher than those of 1 and 4 veins (P < 0.05). Conclusion TTE for diagnosing partial SAPVC and identifying the drainage site of SVC has a high error rate of misdiagnosis and missed diagnosis. The extra attention should be given to these factors in clinical practice to improve the accuracy of TTE in diagnosing SAPVC.

Application of multi-slice spiral CT and abdominal ultrasound in clinical diagnosis of acute appendicitis in children / 中国基层医药

Objective:To investigate the application value of multi-slice spiral CT and abdominal ultrasound methods in the clinical diagnosis of acute appendicitis in children.Methods:We included 50 children patients who were pathologically diagnosed with acute appendicitis by the Department of Surgery, Dongyang Maternal and Child Health Hospital from August 2016 to August 2019. Before surgery, all patients underwent multi-slice spiral CT and abdominal ultrasound examinations. We recorded the time taken to complete multi-slice spiral CT and abdominal ultrasound examinations. Taking pathological results as the diagnosis criteria, we also calculated the coincidence rate of each imaging method.Results:The time we took to complete multi-slice spiral CT examination was shorter than that for abdominal ultrasound examination [(13.34 ± 3.86) minutes vs. (23.45 ± 4.77) minutes, t = 11.65, P < 0.05]. The coincidence rate of multi-slice spiral CT in identifying acute simple appendicitis, acute phlegmonous appendicitis, and acute gangrenous appendicitis was 95.24%, 95.00%, and 100.0%, respectively, and it was 71.73%, 70.00%, 88.89%, respectively for abdominal ultrasound examination. The coincidence rates in identifying acute simple appendicitis, acute phlegmonous appendicitis, and acute gangrenous appendicitis were significantly different between multi-slice spiral CT and abdominal ultrasound examinations ( χ2 = 4.29, 4.33, 1.06, all P < 0.05). Conclusion:Compared with abdominal ultrasound, multi-slice spiral CT is easier to operate, takes a shorter time in manipulation, provides more distinct images, and has a higher coincidence rate. Therefore, multi-slice spiral CT is of great diagnostic value for acute appendicitis in children.

Diagnostic value of combination of VCA-IgA and multilayer enhanced spiral CT in the diagnosis of nasopharyngeal carcinoma / 国际检验医学杂志

Objective To investigate the diagnostic value of VCA-IgA and multilayer enhanced spiral CT(MESCT) in the diagnosis of nasopharyngeal carcinoma.Methods Retrospective analysed the data on serum VCA-IgA test and MESCT of 385 patients with suspected nasopharyngeal disease,and the results were confirmed by surgery and pathology.Comparatively analysed the two methods in differential diagnosis of nasopharyngeal carcinoma and benign diseases.Finally,calculated the sensivity,speficity,positive predictive value,negative predictive value and accuracy in diagnosis of nasopharyngeal carcinoma.Results The positive rate of serum VCA-IgA,MESCT and combination of those two methods in naospharyngeal carcinoma were significantly higher than those in nasopharyngeal benign disease(P<0.05);combination of the methods significantly improve the sensitivity and accuracy in diagnosis of nasopharyngeal carcinoma,the specificity was lower than VCA-IgA,higher than MESCT alone.Conclusion Combination of serum VCA-IgA and MESCT were excellent strategy for diagnosis of nasopharyngeal carcinoma.
