摘　　要：目的探讨多层螺旋CT(MSCT)及图像后处理技术对胰源性区域性门静脉高压的诊断及临床价值。方法对胰源性区域性门静脉高压症患者28例使用16排多层螺旋CT机行腹部平扫及增强扫描,采用图像后处理技术,显示胰源性区域性门静脉高压异常的脾静脉及侧支血管情况。结果 CT显示脾静脉狭窄或闭塞28例,胃冠状静脉曲张14例(14/28),胃短静脉曲张15例(15/28),胃网膜静脉曲张25例(25/28)。结论 MSCT及图像后处理技术能很好地从不同方位显示胰源性区域性门静脉高压侧支循环血管,具有重要的临床指导价值。Objective To investigate the value of multi-slice CT（MSCT） post-processing techniques in clinical settings and imaging diagnosis of pancreatogenic regional Portal Hyertension （PRPH）. Methods A 16-detector row spiral CT scanner was used to perform plain and muti-phase contrast enhanced abdominal scanning in 28 patients with PRPH. Vari- ous image post-processing techniques were applied to depict abnomal splenic vein and the collateral vessels of PRPH. Re- stilts Splenic veins showed stricture Or occlusing in all 28 cases. Tortuous and dilated varicose veins were displayed at va- rious locations including coronary gastric vein （14/28）, short gastric vein （15/28） and gastroepiploic vein （25/28）. Con- clusion MSCT and image post-processing techniques are very effective for displaying the collateral circulation of PRPH, which is very significant in clinical practice.
