作者研究了双期螺旋扫描中应用不同碘浓度对肝脏强化和肝局灶性病变检出的影响。作者将102例肝局灶性病变的病人随机分至A或B两个螺旋CT扫描方案组。两组病人的年龄、体重和主要特征在统计学上并无显著性差异。CT扫描包括平扫和增强(动脉期和门静脉期),两组病人均给予180ml的碘普罗胺。其中A组使用370mg/ml的碘浓度。而B组的碘浓度为300mg/ml,两组均使用相同的注药方法、速度和延迟扫描时间。在动脉期和门静脉期两个
The authors studied the effects of different concentrations of iodine on the detection of hepatic enhancement and focal hepatic lesions in two-phase spiral scans. The authors randomized 102 patients with focal hepatic lesions to A or B two spiral CT scan groups. There were no statistically significant differences in age, weight, and major characteristics between the two groups. CT scans included both plain and enhanced (arterial and portal) phases, and 180 mL of iopromide was administered to both groups. Group A used iodine concentration of 370mg / ml. The iodine concentration in group B was 300 mg / ml, and both groups used the same injection method, speed and delayed scan time. Two in the arterial and portal venous phases
