作者应用单一层面肝动脉造影薄层动态CT扫描(SLDTS-CTHA)结合对切除标本的组织学研究,评价富血供肝细胞癌(HCC)血流动力学以确定肿瘤主要引流血管。32例HCC患者普通肝动脉造影CT发现32个直径9～53mm(平均25mm)的高密度瘤灶,SLDTS-CTHA时肝动脉内注射320mgI/ml对比剂10ml(1ml/s),层厚1mm(22例)或3mm(10例),以1s间距重建图像。对包括本组9例在内的40个手术切除标本进行组织学检查,其中一个
The authors used a single-slice hepatic arterial angiography thin-layer dynamic CT scan (SLDTS-CTHA) combined with histological studies of resected specimens to evaluate hemodynamics of hemagglutinated hepatocellular carcinoma (HCC) to determine the main drainage of blood vessels. Thirty-two HCC patients with common hepatic arterial angiography found 32 high-density tumors with a diameter of 9-53mm (average 25mm). In SLDTS-CTHA, intrahepatic artery injection of 320mgI/ml of contrast agent (10ml/s) and a layer thickness of 1mm was performed. In 22 cases) or 3 mm (10 cases), images were reconstructed with a 1 s pitch. Histological examination of 40 surgical specimens including 9 cases in this group was performed.
