摘　　要：目的研究超微血管成像(SMI)、彩色多普勒血流成像(CDFI)和增强电子计算机断层扫描(CT)检测经肝动脉灌注化疗栓塞(TACE)术治疗的原发性肝癌(PLC)患者肿瘤血供显像的效果。方法2016年4月~2019年4月我院收治的135例PLC患者,所有患者均接受TACE术治疗,于术后30 d接受SMI、CDFI和增强CT检查。结果SMI和CDFI病灶血供检出率分别为54.2%和25.0%,均显著低于增强CT检测的84.5%(P<0.05);针对直径<2.0 cm的病灶,SMI和CDFI血供检出率分别为28.1%和0.0%,显著低于增强CT检测的73.7%(P<0.05);针对直径≥2.0 cm的病灶,SMI和CDFI血供检出率分别为67.6%和37.8%,也显著低于增强CT检测的90.1%(P<0.05)。结论在TACE术后,使用CT检查病灶血供最具有价值,其他检查可能简便,起辅助作用。Objective The aim of this study was to investigate the efficacy ofultramicro-angiography(SMI),color Doppler flow imaging(CDFI)and enhanced computed tomography(CT)in detecting tumor blood supply in patients with primary liver cancer(PLC)after transcatheter arterial chemoembolization(TACE).Methods 135 patients with PLC were admitted to our hospital between April 2016 and April 2019,and all patients underwent TACE and received SMI,CDFI and enhanced CT scan 30 days after operation.Results The detection rates of tumor blood supply by SMI and CDFI were 54.2%and 25.0%,respectively,both significantly lower than 84.5%by enhanced CT(P<0.05);for lesions with diameter<2.0 cm,the tumor blood supply detection rate by SMI and CDFI were28.1%and 0.0%,respectively,both significantly lower than 73.7%by enhanced CT(P<0.05),and for lesions with diameter≥2.0 cm,the detection rate of tumor blood supply by SMI and CDFI were 67.6%and 37.8%,respectively,both significantly lower than 90.1%by enhanced CT(P<0.05).Conclusion The application of enhanced CT scan in evaluating tumor blood supply after TACE in patients with PLC might be useful in clinical practice,and SMI and CDFI are simple,convenient and economical.
