急性胰腺炎的CT诊断

CT diagnosis of acute pancreatitis

目的探讨CT对急性胰腺炎的诊断价值。方法回顾性分析32例经临床证实急性胰腺炎患者的CT资料,观察其CT表现特征,全部患者均经腹部CT平扫,其中6例又经增强扫描。结果急性轻症胰腺炎19例,急性重症胰腺炎13例。CT主要表现为胰腺弥漫性增大,密度降低,其中,9例有不规则低密度区,17例有胰周积液,1例胰腺内见局限性斑点状高密度出血影。结论 CT检查是诊断急性胰腺炎及其并发症的重要方法。

Objective To evaluate the value of CT scanning in the diagnosis of acute pancreatitis（AP）.Methods Thirty-two patients with AP proved clinically underwent CT plain scan of abdomen,contrast enhanced CT scans were performed on 6 of them in addtion.CT findings of all patients were retrospectively analyzed.Results The study demonstrated that there were 19 mild AP and 13 severe AP in the group.Lesions mainly appeared as diffuse swelling of pancreas associated with density decreasing.The irregular hypodense zones were found in 9 cases,the peripancreatic effusion in 17 cases and the localized mottling hemorrhagic shadows with hyperdensity in 1 case.Conclusion CT scan is an important method for diagnosis of AP and its complications.
