目的 探究64排螺旋CT成像对门 静脉高压症的诊断价值。方法 对2013年3 月至2014年3月我院收治的160例诊断为门 静脉高压症的患者进行64排螺旋CT门静脉 成像检查，并对其容积数据进行重建，分 析患者的门静脉及其属支以及侧支循环的 影像学特征。结果 门静脉主干和脾静脉 等属支在64排螺旋CT成像技术下均能清楚 地显示，根据其影像学表现可初步评估门 脉高压症的程度及其主要疾病，亦能清楚 地判断侧支循环的分布范围。结论 对门 静脉高压症患者进行64排螺旋CT成像检查 可以提高对门静脉高压症患者症状发展程 度判断的准确性，为临床治疗提供极大的 辅助功能，值得在临床上推广应用。

Objective To explore the diagnostic value of 64 row spiral CT in detection of portal hypertension. Methods 160 patients with portal hypertension in our hospital from March 2013 to March 2014 were checked by 64 row spiral CT and the volume data was reconstructed. The imaging characteristics of patients' portal vein and its branches and collateral circulation were analyzed. Results The main portal vein and its branches like splenic vein can be clearly showed by 64 row spiral CT, and the degree of portal hypertension and the major diseases can be preliminary assessed through their imaging manifestations, and the distribution range can be judged clearly. Conclusion The accuracy of diagnosis of the patients with portal hypertension can be improved by 64 row spiral CT, which is worth popularizing in clinic.
