急性胰腺炎患者的CT、MRI影像学表现及其诊断价值对比研究

A Comparative Study of CT and MRI Image Findings and Diagnostic Value in Patients with Acute Pancreatitis

目的:比较急性胰腺炎患者的电子计算机断层扫描(CT)、磁共振成像(MRI)影像学表现及其诊断价值.方法:选择2018年1月-2019年12月我院收治并初步诊断为急性胰腺炎的患者124例,所有患者均同时行CT和MRI检查,并比较两种检查方式诊断急性胰腺炎的影像学表现,以临床最终诊断结果作为参考,比较两种检查方式诊断急性胰腺炎的价值.结果:124例患者,经临床最终诊断为急性胰腺炎96例,28例为非急性胰腺炎,以临床最终诊断结果为"金标准",CT诊断急性胰腺炎的灵敏度、特异度、阳性预测值、阴性预测值和准确度分别为84.38%、75.00%、92.05%、58.33%、82.26%,MRI诊断急性胰腺炎的灵敏度、特异度、阳性预测值、阴性预测值和准确度分别为95.83%、78.57%、93.88%、84.62%、91.94%,MRI诊断急性胰腺炎的灵敏度、阴性预测值和准确度显著高于CT(P<0.05),两种检查方式诊断急性胰腺炎的特异度、阳性预测值比较无统计学差异(P>0.05).结论:CT和MRI影像学表现有利于急性胰腺炎的诊断,两者对急性胰腺炎诊断均具有较高的灵敏度、特异度和准确度,但MRI诊断急性胰腺炎的灵敏度、准确度优于CT.

Objective: To compare the computed tomography(CT), magnetic resonance imaging(MRI) image findings of patients with acute pancreatitis and their diagnostic value. Methods: 124 patients who were admitted to our hospital and initially diagnosed as acute pancreatitis from January 2018 to December 2019 were selected. All patients were examined with CT and MRI examination at the same time. The image findings of the two examination methods of diagnosis of acute pancreatitis, were compared. With the clinical final diagnosis results as a reference, the value of the two examination methods in the diagnosis of acute pancreatitis were compared. Results:Of the 124 patients, 96 were diagnosed as acute pancreatitis, and 28 were non-acute pancreatitis. Take the final clinical diagnosis result as the "gold standard", the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT in the diagnosis of acute pancreatitis were 84.38%, 75.00%, 92.05%, 58.33% and 82.26% respectively. The sensitivity, specificity, positive predictive value,negative predictive value and accuracy of MRI in the diagnosis of acute pancreatitis were 95.83%, 78.57%, 93.88%, 84.62% and 91.94%,respectively. The sensitivity, negative predictive value and accuracy of MRI in the diagnosis of acute pancreatitis were significantly higher than those of CT in the diagnosis of acute pancreatitis(P<0.05). There were no significant differences between the two examination methods in specificity and positive predictive value(P>0.05). Conclusion: CT and MRI image findings are helpful for the diagnosis of acute pancreatitis. Both of them have high sensitivity, specificity and accuracy. However, the sensitivity and accuracy of MRI in the diagnosis of acute pancreatitis are better than that of CT.
