摘　　要：目的:探讨胰腺撕裂伤的CT表现。方法:搜集18例经临床手术证实的胰腺撕裂伤病例资料,分析其CT平扫及增强表现。普通CT扫描层厚5mm,螺旋CT均行薄层多平面重组(MPR)。结果:胰腺内血肿3例,胰腺局限或弥漫性肿胀11例,网膜囊积液12例,胰周积液及左侧肾前筋膜增厚18例,平扫9例胰腺实质内可见低密度撕裂口,增强扫描所有病例胰腺实质内均可见低密度撕裂伤口,其中胰头5例,胰颈8例,胰腺体尾部5例。主胰管损伤CT诊断符合率70%。合并其他脏器损伤12例。结论:胰腺撕裂伤有较特征性的CT表现,CT薄层增强扫描可准确诊断胰腺撕裂伤。CT对主胰管损伤的判断有一定的限度。Objective：To study the CT findings of pancreatic laceration. Methods：Data of 18 cases of pancreatic laceration confirmed by operation were collected,and the CT fingdings of plain and enhancement scans were analyzed. The slice is 5ram in conventional CT, thin slice three-dimension reconstruction was performed,and the application of enhancement scan was emphasized. Results：CT manifestation of pancreastic laceration included： pancreatic hemotoma in 3 cases,partial or diffuse swelling of pancreas in 11 cases, fluid collection in omental bursa in 12 cases, peripancreatic fluid collections and left Gerota＇s fascia thicking in 18 cases,pancreatic split was found in 9 cases on plain scan,and it was found in all cases on postcontrast images. The laceration of pancreatic head was shown in 5 cases, the laceration of pancreatic neck in 8 cases, the laceration of pancreatic body and tail in 5 cases, the CT diagnostic correspondent ratio of rupture of Wirsung＇s duct was 70 %, meanwhile the contusion of other organs was found in 12 cases. Conclution：The pancreatic laceration has characteristic CT findings, CT thin-slice enhancement scan can correctly diagnose pancreatic laceration. CT diagnosis for rupture of Wirsung＇s duct is limited.
