肝动脉造影与门静脉造影CT诊断肝癌体会

Helical CT during arterial portography combined with hepatic arteriography in detection of hepatocelhllar caranoma

探讨肝动脉造影结合门静脉造影CT诊断细胞肝癌的应用价值。15例患者分别行选择性肝动脉造影及门静脉造影检查。9例肝细胞肝癌被检出,其中肝动脉造影显示肿瘤血管及结节状肿瘤染色;门静脉造影CT显示肝脏相应部位低密度灶,部分周边略显强化,其形态大小及位置均与肝动脉造影所显示的病灶一致,肿块大小为2.0～5.0cm,9例均经手术后病理证实。肝动脉造影结合门静脉造影是诊断肝细胞癌的有效方法,对病灶的检出率明显高于其他检查。

To discuss the diagnostic value of helical CT during arterial portography(CTAP) combined with hepatic arteriography in detection of hepatocellular carcinoma( HCC). CTAP and hepatic arteriography were perfomied on 15 patients suspected HCC.9 cases HCC were detected by CTAP and hepatic arteriograthy. The size and the location of the HCC were identical in both examinations. HCC were hypoattenuation on CTAP, hyperattenuation on hepatic arteriography. All 9 cases were confirmed as HCC by pathology. Helical CT during arterial portography combined with hepatic arteriography is more effective examination to diagnose HCC than others.
