| 摘 要： | 目的探讨16层CT的各种血管成像方法对胰头静脉弓的正常表现及显示率方法对40例非腹部疾病患者行胰腺静脉期扫描,使用轴位图像、薄层最大密度投影(TSMIP)和容积再现(VR)图像分别评价胰头静脉弓的表现及显示率结果轴位图像、TSMIP和VR显示胃网膜右静脉均为100%,胃结肠干均为80%,右结肠上静脉分别为100%、87.5%、80%;胰十二指肠上后静脉分别为92.5%、65%、40%;胰十二指肠上前静脉分别为92.5%、62.5%、45%结论使用16层CT,联合轴位、TSMIP和VR图像可以清楚显示胰头静脉弓

| Abstract: | Objective To evaluate the features and visualization of venous arcades of the pancreatic head (VAPH) using 16-slice CT with different techniques.Methods Portal-phase CT scanning with 16-slice CT was performed in 40 cases.The visualized rate of VAPH with axial images,thin slice maximum intensity projection(TSMIP) and volume rendering(VR) was assessed.Results With axial images,TSMIP and VR,the visualized rate of right gastro-epiploic vein and gastro-colic vein were all 100% and 80% respectively;while for right colic superior vein was 100%,87.5% and 80%;pancreaticoduodenal posterior-superior vein was 92.5%,65% and 40%;pancreaticoduodenal anterior-superior vein was 92.5%,62.5% and 45% respectively.Conclusion VAPH can be showed definitely using 16-slice CT in combination of axial images,TSMIP and VR images. |
