摘要
目的:探讨原发性肝癌肝动脉灌注栓塞后非坏死低密度区血供的多层螺旋CT分型及其临床意义。方法:32例肝癌患者肝动脉灌注栓塞后行多层螺旋CT肝脏增强双期扫描,6例同时行肝动脉、门静脉容积重建技术、曲面重建技术、表面成像和最大密度投影三维重建。结果:32例肝癌患者肝动脉灌注栓塞后非坏死低密度区CT平扫表现分为三个类型:周边型16例、侧边型5例、混合型11例;其血供分为四种类型:肝动脉供血型20例、门静脉供血型5例、双重供血型5例、少血供型2例。6例肝动脉和门静脉三维重建较好地显示了血管与非坏死低密度区之间的关系。结论:多层螺旋CT双期扫描及血管三维重建对肝癌肝动脉灌注栓塞后肿瘤内非坏死低密度区血供的诊断有重要价值,并对继续治疗方案的选择与制定有一定的临床意义。
Objective： To assess the value of muhidetector -row computed tomoraphy （MDCT） in choosing retreatment methods of hepatocellular carcinoma （HCC） through evaluating the blood supply of low - density area of HCC after transcatheter arterial chemoembolization （TACE）. Methods： Thirty -two patients with HCC after TACE treaanent were examined by plain scanning and hepatic mnhidetector -row CT. The location of low -density area on plain scanning and the enhancement patterns on dynamic contrast -enhanced scanning were observed. At the same time, threedimensional CT （3D CT） models of the volume rendering, curved muhiplanar reformations, surface shaded display and maximum intensity projection reconstruction of the hepatic artery and portal vein were performed in 6 cases. Rerults： In CT plain scanning data, low density areas of 32 cases of HCC after TACE treatment were divided into three types： peripheral, one -side -located and mixed types. In contrast -enhanced CT scans, the blood supply of low -density area was classified into four types： arterial blood supply （20 cases）, portal blood supply （5 cases）, arterial combining with portal blood supply （5 cases） and poor blood supply （2 cases）. In the 6 cases, the relationship between the low -density area and branches of hepatic artery as well as portal vein was showed by 3D CT. Concision： Hepatic MDCT is an effective method in evaluating the blood supply of low - density area and the therapeutic effect of HCC after TACE treatment. Types of blood supply give us the selection of retreatment.
