摘要 目的:探讨能谱CT鉴别原发性肝癌经肝动脉灌注化疗栓塞术(transcatheter arterial chemoembolization,TACE)后早期新增乏血供病灶活性的价值。方法:回顾性分析2018年9月至2019年9月因原发性肝癌在徐州市肿瘤医院行TACE术后1~3个月能谱CT增强扫描复查的49例患者,从中发现新增病灶75个,其中55个为乏血供病灶。以数字减影血管造影技术(digital subtraction angiography,DSA)及影像后续随访形态学特征为金标准,把55个乏血供病灶分为阳性组与阴性组,统计两组病灶动、静脉期的碘浓度和能谱曲线斜率。结果:原发性肝癌经TACE后复查,早期新增阳性及阴性乏血供病灶的能谱CT扫描参数有明显差异,有统计学意义。结论:能谱CT获得动、门静脉期碘浓度及能谱曲线斜率等参数对鉴别肝癌TACE后早期新增乏血供病灶活性有一定的价值,对临床后续治疗有重要意义。
