Gravity reduces the
blood flow and T2 of the kidney. Multiposture MRI makes it possible
to evaluate the effect of gravity on regional kidney function.

MRI. Regions of interest (yellow open circles) on the (c) velocity, (d) T2,
(e) T2’, and (f) apparent diffusion coefficient (ADC) images.

renal blood flow of the (a) right and (b) left kidneys, and (c) heart rate in
the supine and upright positions.
