目的:研究急性胰腺炎运用CT检查的诊断价值以及鉴别诊断。方法:我院选择2012年8月~2013年8月间诊治的56例急性胰腺炎患者,所有患者均运用CT进行检查,对其临床表现以及影像学表现进行分析,所有患者均进行CT平扫,其中2例患者具有碘过敏,无法实施增强扫描,其余的54例患者均进行CT增强扫描检查。结果:本文所选的患者中,36例为中轻型急性胰腺炎,经过CT检查可见有程度不等的胰腺体积弥漫性增大,经过CT检查胰腺体积更大,密度降低,内部可见高密度出血灶,肾前筋膜及胰周可见大量积液,同时可伴有腹腔明显积液。结论:通过对胰腺组织的影像学表现,分期进行分级,诊断、鉴别诊断、病情评估,尤其是对轻、重症胰腺炎患者,需要查看是否对周围器官产生影响,在判断是否为胰腺坏死时可运用增强CT检查进行诊断。 Objective: To study the diagnostic value and differential diagnosis of acute pancreatitis using CT examination. Methods: A total of 56 patients with acute pancreatitis who were diagnosed and treated between August 2012 and August 2013 in our hospital were selected. All patients were examined by CT. The clinical manifestations and imaging findings were analyzed. All patients underwent CT scan Two of the patients had iodine hypersensitivity and were unable to perform an enhanced scan. The remaining 54 patients underwent CT-enhanced scans. Results: Among the patients selected in this study, 36 cases were mild-to-severe acute pancreatitis. Pancreas volume diffusely increased after CT examination. Pancreas volume and density decreased after CT examination. High-density bleeding was seen inside Focal, renal fascia and peripancreatic fluid can be seen a lot, at the same time can be associated with significant abdominal fluid. Conclusion: Through the imaging findings of pancreatic tissues, staging classification, diagnosis, differential diagnosis, disease evaluation, especially for patients with mild and severe pancreatitis, need to see whether the impact on the surrounding organs, in determining whether the pancreatic necrosis can be Use enhanced CT examination for diagnosis.
