目的 :评价多层螺旋CT双动脉期扫描在肝细胞癌诊断中的价值。方法 :2 1例患者共 3 3个肝细胞癌行双动脉期扫描 ,以3ml s的速度经肘静脉注入非离子型造影剂 10 0ml后 18～ 2 0s ,3 8～ 41s扫描分别获得动脉早期和动脉晚期图像。结果 :动脉早期有 17例显示肿瘤供血动脉及异常血管网 ,2例结节型肝癌呈现高密度强化。动脉晚期 1例结节型无明显强化 ,8例肿块型表现为不均匀强化外 ,其余结节型及肿块型均呈明显高密度强化。结论 :多层螺旋CT双动脉期扫描可较好显示肿瘤血管 ,有利于多血供肿瘤病灶及小病灶的检出。
Objective: To evaluate the value of multislice spiral CT double-phase arteriography in the diagnosis of hepatocellular carcinoma. Methods: Twenty-three patients with hepatocellular carcinoma were enrolled in this study. Two 20-second and 30 -41s scans of non-ionic contrast medium were injected into the elbow vein at a speed of 3ml s And late arteries. Results: In the early stage of arteries, 17 cases showed tumor feeding artery and abnormal vascular network, and 2 cases showed nodular liver cancer with high density enhancement. One case of advanced nodular nodules no significant enhancement, 8 cases showed heterogeneous mass enhancement, the other nodules and mass showed significant high density enhancement. Conclusion: Multi-slice spiral CT double-arterial phase scan can better display tumor blood vessels, which is conducive to the detection of blood-rich tumor and small lesions.
