补充资料:大剂量增强后延迟CT


大剂量增强后延迟CT


  CT检查方法之一。用于检查肝脏占位性病变的增强CT技术。使用总量为60g碘的经尿路排泄的对比剂,经静脉注入后延迟4~6小时后进行CT扫描。该法不同于一般在增强后5~15分钟的延迟扫描。主要原理是:注入的对比剂中约有1%~2%将滞留于正常肝实质内,最后经胆道排泄,从而使正常肝组织的密度值比平扫时增高约20HU,而肝内病灶区内无对比剂滞留,表现为低密度,形成对比。应注意的是此时肝内血管亦无对比剂滞留而呈低密度,因此需结合增强CT(包括普通增强、动态团注增强或血管造影CT)比较判断。该法可使肝内小占位性病灶的检出率提高约20%~30%。
