螺旋CT门静脉造影的临床应用

目的 探讨螺旋ＣＴ门静脉造影（ＣＴＰ）对门静脉系统的显示能力，评价其在该系统的临床应用价值。方法 １６０例 颖有肝脏疾病的患者进行了ＣＴＰ检查，其中经手术治疗者４７例，常规血管造影者１２例，以此为对照，对肝脏肿瘤定位及门静脉癌栓、门脉高压侧支循环的显示情况和不同疾病的ＣＴＰ表现做一分析。结果 ＣＴＰ能清晰成像门静脉系统，精确定位肝内病灶（１００％）。ＣＴＰ原始图像的ＣＴＰ表现做一分析。结果 ＣＴＰ

Clinical application of spiral CT portography

Objective To evaluate the ability of spiral CT portography (CTP) to image the portal vein and its diagnostic value. Methods CTP was performed in 160 cases suspected of hepatic disease. 47 patients received surgical treatment and 12 with routine angiography. The demonstration of the location of hepatic lesions, the portal vein tumor thrombosis and the collateral circulation in portal hypertension, and the CTP findings in a variety of diseases were analyzed. Results The portal vein could be distinctly displayed by CTP. It could exactly locate the hepatic lesions (100%) and the accurate rate of finding the portal vein tumor thrombosis was 100% with CTP natural images and multi-projection volume reconstruction (MPVR), and it also could show the range of collateral circulation and estimate its degree. It could be used in a spectrum of abnormalities. Conclusion CTP is a noninvasive, reliable, and valuable method for the assessment of portal venous system.
