The postcontrast CT scans and angiography of 26 lesions in 23 patients with hepatomas who underwent transcatheter arterial embolization therapy were reviewed. Newly developed low density and high density areas and gas were noted on CT scans of the tumors after embolization in 100, 8 and 58% of the lesions, respectively. The CT findings of residual tumors correlated well with those of follow-up angiography. When discrete smooth round low density zones were observed on CT, there was no residual neovascularity on follow-up arteriography. When there were nodular or thick septum-like structures in low density lesions, arteriography revealed residual tumor vascularity in the lesions. CT proved useful not only in evaluating the effects of embolization, but also in providing important information about residual tumors.
回顾了23例接受经导管动脉栓塞治疗的肝癌患者26个病灶的增强CT扫描和血管造影结果。栓塞后，分别在100%、8%和58%的病灶的CT扫描中发现肿瘤出现新的低密度区、高密度区和气体。残留肿瘤的CT表现与随访血管造影结果相关性良好。当CT上观察到离散的光滑圆形低密度区时，随访动脉造影显示无残留新生血管。当低密度病灶中存在结节状或厚间隔样结构时，动脉造影显示病灶中有残留肿瘤血管。CT不仅在评估栓塞效果方面有用，而且在提供有关残留肿瘤的重要信息方面也很有用。
