作者收集了12例经证实的肝局灶性结节增生(FNH),重点讨论了肝脏FNH在三期螺旋CT中之非典型表现,并与以往文献所述之典型CT征象作了比较。12例肝FNH的三期螺旋CT扫描方法是先以5ml/s的速度团注20ml对比剂,在腹腔动脉水平扫描,以测定主动脉强化峰值时间,然后团注180ml对比剂在峰值后5s、注药后60s以及12～15min时分别作动脉期、门脉期和延迟期扫描,层厚5mm。结果仅2例FNH符合常规增强CT的典型
The authors collected 12 cases of confirmed focal nodular hyperplasia (FNH), focusing on atypical findings of hepatic FNH in triple-phase spiral CT and compared with the typical CT findings described in previous literature. Twelve cases of liver FNH by three-phase spiral CT scan method is first 5ml / s speed group bolus 20ml contrast agent in the celiac artery scan level to determine the peak aortic enhancement time, and then bolted 180ml contrast agent peak 5s, After injection of 60s and 12 ~ 15min, respectively, for the arterial phase, portal phase and delayed scanning, layer thickness 5mm. Results Only two cases of FNH were found to be typical of conventional enhanced CT
