作肝癌动脉栓塞时,往往要作右膈下动脉选择性造影和栓塞,而膈下动脉起始部变异甚多,有的会使选择性插管很费时。因此,作者对在栓塞术前全肝动态CT扫描能否确定右膈下动脉起始部作了研究。对象是肝细胞癌30例,在血管造影的作全肝动态CT扫描。血管造影时,除右膈下动脉从腹腔动脉发出者外,其余均作选择性右膈下动脉造影,确认其起始部。CT扫描的对比剂用碘苯六醇90ml,注入速度为3ml/s。从开始注入30s后作全肝螺旋扫描,X线束宽10mm,进床速度10mm/s,图像重建除2例厚5mm外,其余均是10mm。这种扫描方式并不是特意为显示有膈下动脉起始部而设计。
For liver cancer arterial embolism, often for the right subphrenic artery selective angiography and embolism, and the origin of the subphrenic artery variability is very large, and some will make selective intubation is time-consuming. Therefore, the author of the embolization before the whole liver dynamic CT scan can determine the beginning of the right subphrenic artery was studied. Thirty patients with hepatocellular carcinoma underwent whole-brain dynamic CT scan in angiography. Angiography, in addition to the right subphrenic artery issued from the celiac artery, the rest were made for selective right inferior phrenic artery angiography to confirm the beginning. CT scan of contrast agent with iophorol 90ml, injection speed of 3ml / s. From the beginning after injection into the 30s for the whole liver spiral scan, X beam width 10mm, bed speed 10mm / s, image reconstruction in addition to two cases of 5mm thick, the rest are 10mm. This scan is not designed to show the onset of the subphrenic artery.
