| Popis: | 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. |
