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
Objective To investigate the performance of 16-slice CT angiography in normal pancreas and the rate of display on 40 patients with non-abdominal diseases undergoing pan-venous venous phase scanning. Axial images, thin-film maximum density projection (TSMIP) and Volume rendering (VR) images were used to evaluate the performance of the pancreas vena cava and its axial rate. The axial images of TSMIP and VR showed that the right gastric vestibule was 100%, the dry colon of the stomach and the intestine was 80%, and the superior colonic vein was 100%, 87.5% and 80% respectively. The posterior pancreaticoduodenal veins were 92.5%, 65% and 40% respectively. The pancreaticoduodenal veins were 92.5%, 62.5% and 45% CT, combined axial, TSMIP and VR images clearly show the pancreas of the pancreas
