作者研究49例病人的79个病灶,其中36例HCC(男25例,女11例),年龄41～80岁,而13例血管瘤年龄36～75岁。36例HCC癌灶大小为8～40mm(平均19.9mm),其中原发性癌灶32个,转移性癌灶19个。血管瘤13例病灶大小为5～29mm(平均10.7mm)。双期动态增强CT扫描是把对比剂碘苯六醇或碘异酞醇(300mgI/ml)平均量120ml(2ml/kg)分为两个时期注射,对比剂的前半量以3ml/s速度注射,然后立 The authors studied 79 lesions in 49 patients, of which 36 were HCC (25 males and 11 females), aged 41-80 years, and 13 were aged 36-75 years. The size of HCC lesions in 36 cases ranged from 8 to 40 mm (average 19.9 mm), including 32 primary lesions and 19 metastatic lesions. Hemangiomas in 13 lesions ranged in size from 5 to 29 mm (average 10.7 mm). In the double-phase dynamic contrast-enhanced CT scan, the average amount of contrast iodobenzene or iso-indoline (300 mgI/ml) was 120 ml (2 ml/kg) divided into two injection periods, and the first half of the contrast medium was injected at 3 ml/s. And then
