作者为确认螺旋CT在动脉、门脉和延迟期发现结节型肝细胞癌的价值,选择了45例患者的81个结节型肝细胞癌三相螺旋CT影像。在以3ml/s注入68％非离子对比剂(2ml)期间,选择10mm层和10mm/s床移动获得影像。分别在注入对比剂后25～30s、60～70s和300s获得动脉相、门脉相和延迟期相。二位复习者双盲分析三相影像对病变的发现和显示程度,三相螺旋CT发现45例患者的81
To confirm the value of spiral CT in the detection of nodular hepatocellular carcinoma in arteries, portal veins, and delayed phases, a three-phase spiral CT scan of 81 nodular hepatocellular carcinoma was performed in 45 patients. During the injection of 68% non-ionic contrast agent (2 ml) at 3 ml/s, a 10 mm layer and 10 mm/s bed movement was selected to obtain images. The arterial phase, portal phase and delayed phase were obtained at 25-30 s, 60-70 s and 300 s after injection of contrast medium. Two reviewers double-blind analysis of three-phase images of the extent of lesion detection and display, three-phase spiral CT found 45 patients 81
