This study was designed to describe tumor feeders from the intercostal artery supplying hepatocellular carcinoma (HCC) on C-arm CT and multidetector row CT. From March 2008 to May 2009, C-arm CT of the intercostal artery was prospectively performed in 24 HCC patients. Two interventional radiologists, who performed C-arm CT, evaluated tumor feeders on C-arm CT and multidetector row CT scans by consensus. In total, 35 intercostal arteries were examined by C-arm CT. All tumor feeders except one showed a sharp upward turn at or near the costochondral junction. On axial C-arm CT images, all tumor feeders were observed as an enhancing dot in the upper intercostal space along the diaphragm. On multidetector CT scans, 17 tumor feeders were observed and 18 were not. Tumor feeders from the intercostal artery are observed as an enhancing dot along the diaphragm on C-arm CT and can be seen on multidetector row CT in approximately half of patients.
本研究旨在描述 C 臂 CT 和多排 CT 上肋间动脉为肝细胞癌（HCC）供血的肿瘤滋养血管。2008 年 3 月至 2009 年 5 月，前瞻性对 24 例 HCC 患者进行 C 臂 CT 肋间动脉检查。两位进行 C 臂 CT 的介入放射科医生通过共识评估 C 臂 CT 和多排 CT 扫描上的肿瘤滋养血管。共检查了 35 根肋间动脉。除 1 根外，所有肿瘤滋养血管均在肋软骨连接处或附近呈锐角向上转弯。在轴位 C 臂 CT 图像上，所有肿瘤滋养血管均在膈肌上沿肋间空间观察到增强的小点。在多排 CT 扫描上，观察到 17 个肿瘤滋养血管，未观察到 18 个肿瘤滋养血管。C 臂 CT 上观察到肿瘤滋养血管呈膈肌上的增强小点，约一半患者可在多排 CT 上看到。
