【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指导价值。方法:对胰源性区域性门静脉高压患者18例,使用16排多层螺旋CT机行上腹部CT平扫及增强扫描,采用多平面重组(MPR)、最大密度投影(MIP)、容积再现(VR)等图像后处理技术,显示胰源性区域性门静脉高压侧支循环血管。结果:显示胃网膜静脉曲张(84%)、胃短静脉曲张(90%)、胃冠状静脉曲张(78%)、胃结肠干曲张(50%)和食管静脉曲张(17%)。MPR、MIP、VR可以直观地显示各曲张血管的走行及曲张程度。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。更多还原

【Abstract】 Objective:To investigate the value of multi-slice CT (MSCT) post-processing techniques in clinical settings and imaging diagnosis of pancreatogenic regional Portal Hypertension.Methods:A 16-detector row spiral CT scanner was used to perform plain and contrast enhanced abdominal scanning in 18 patients with pancreatogenic regional Portal Hypertension.Various image post-processing techniques such as MPR,MIP,VRT,were applied to depict the collateral vessels of pancreatogenic regional Portal Hypertension.Results:Tortuous and dilated varicose veins were displayed at various locations including gastroepiploic vein (GEV,85%),short gastric vein (SGV,90%),coronary gastric vein (CGV,78%),gastrocolic trunk (GCT,50%) and esophageal vein (EV,17%).The course and extent of every varicose vessel could be displayed directly by MPR,MIP and VR.Conclusion:In patients with pancreatogenic regional,MSCT and image post-processing techniques are very effective for displaying the collateral circulation of Portal Hypertension various location,which is very significant in clinical practice.更多还原
