2 Figure 1 Magnetic resonance (MR) angiogram of the renal arteries in a patient with autosomal-dominant polycystic kidney disease (ADPKD). (A) Following the MR angiogram a flow acquisition MR pulse sequence (see Methods section for detailed description) is performed perpendicular to the renal artery. (B) The flow acquisition pulse sequence yields a set of cross-sectional images through the renal arteries and veins. Flow analysis is performed on the MR signal information contained within the renal artery.

3 Figure 2 Analyses of patient with autosomal-dominant polycystic kidney disease (ADPKD). (A) Velocity, cross-sectional area, and blood flow plotted during 20 phases of the cardiac cycle in the left renal artery in a magnetic resonance (MR) flow acquisition of an ADPKD patient. (B) Cross-sectional flow acquisition images in the left renal artery of the same patient.

4 Figure 3 Blood flow measurements repeated three times in 19 autosomal-dominant polycystic kidney disease (ADPKD) patients by radiologists A and B. The intrareviewer coefficients of variation were 1.2% and 1.4%. The average interreviewer coefficient of variation was 2.5%.
