Two independent measurements of total renal blood flow (RBF) were made in healthy human subjects (n = 14, mean age 30 yr) by CINE phase-contrast magnetic resonance angiography. RBF, measured by summing the flows measured in the right and left renal arteries, was 1152 +/- 44 ml/min (mean +/- SE). RBF, measured from the difference between supra- and infrarenal abdominal aorta flow, was 1109 +/- 68 ml/min. Regression analysis of the comparison of these two different RBF calculations yielded a correlation coefficient of 0.72 at a p < .05 level of significance. Based on other studies of RBF in normal subjects by para-aminohippuric acid (PAH) clearance, the expected RBF in this subject group was 1211 +/- 62 ml/min. The results indicate that noninvasive measurement of RBF is possible using phase-contrast magnetic resonance methods.
通过电影相位对比磁共振血管造影术，对健康人体受试者（n = 14，平均年龄30岁）进行了两次独立的总肾血流量（RBF）测量。通过将左右肾动脉测量的血流量相加来测量的RBF为1152 +/- 44 ml/分钟（平均值 +/- 标准误）。通过测量肾动脉上、下腹部主动脉血流量之间的差异来测量的RBF为1109 +/- 68 ml/分钟。对这两种不同RBF计算方法的比较进行回归分析，在p < 0.05的显著性水平下，相关系数为0.72。根据其他通过对氨基马尿酸（PAH）清除率对正常受试者进行的RBF研究，该受试者组的预期RBF为1211 +/- 62 ml/分钟。结果表明，使用相位对比磁共振方法可以进行RBF的无创测量。
