慢性肝病患者的肝内可出现各种结节性病变。作者对腹部血管造影(包括DSA)显示的无浓染的肝结节病变进行了门脉CT成像(CTAP)检查,研究其血流动态变化与病变发展的关系,并作了随访观察。选自1991～1996年间的13例,男6例,女7例,年龄48～76岁,发现结节23个。将碘对比剂(300mg I/ml)稀释2～3倍,取100ml经肠系膜上动脉注入,速度0.7～1.7ml/s,30～40s后行全肝静息扫描,床移动速度10mm/s,层厚10mm,每1层扫描 A variety of nodular lesions can occur in the liver of patients with chronic liver disease. The authors examined portal venous CT imaging (CTAP) of non-stained hepatic nodules revealed by abdominal angiography (including DSA) to investigate the relationship between the dynamic changes of blood flow and the development of the disease and were followed up. Thirteen selected from 1991 to 1996, 6 males and 7 females, aged 48 to 76 years, 23 were found nodules. The iodine contrast agent (300mg I / ml) diluted 2 to 3 times, take 100ml by the superior mesenteric artery infusion rate of 0.7 ~ 1.7ml / s, 30 ~ 40s after the whole liver resting scans, bed movement speed 10mm / s, Layer thickness of 10mm, each layer scan
