急性胰腺炎的CT评价

目的：探讨急性胰腺炎及其并发症的CT表现和急性胰腺炎严重程度的评价方法。方法：回顾CT诊断急性胰腺炎及其并发症、评价急性胰腺炎严重程度的文献。结果：CT增强扫描早期判断胰腺坏死的检测率为90％，而对发病4d后评价胰腺坏死的敏感性几乎为100％，急性胰腺炎CT严重度指数与胰腺局部并发症的发生和急性胰腺炎死亡率有极好的相关性。结论：CT增强扫描能显示胰腺坏死、评价炎性过程的范围和发现局部并发症，是综合评价急性胰腺炎的首选影像学方法。

Comprehensive CT Evaluation of Acute Pancreatitis

Objective To investigate the CT manifestations of acute pancreatitis (AP) and its complications and to evaluate the imaging modalities for staging the severity of AP. Methods Literatures on CT manifestations of AP and its complications and severity staging of AP were reviewed. Results CT has shown an early overall detection rate of 90 % for pancreatic necrosis with close to 100 % sensitivity 4 days after episode. The CT severity index has shown a strongly positive correlation with the development of local complications and mortality of AP. Conclusion Contrast-enhanced CT is the imaging modality of choice to help detect pancreatic necrosis, stage the severity of the inflammatory processes, and depict local complications.
