We assessed the effect of gravity on regional kidney function in the supine and upright positions using an original MRI that can obtain functional information in any posture (multiposture MRI). We compared the mean blood flow, T2, and T2’, apparent diffusion coefficient of the kidney between the supine and upright positions. Gravity reduced the blood flow and T2 of the kidney, and these differences between postures potentially provide new diagnostic information.
