FEASIBILITY OF MR DIFFUSION STUDIES IN THE KIDNEY

Renal apparent diffusion coefficients (ADCs) were anisotropic within a nd significantly different between cortex and medulla using a relative ly motion-insensitive one-dimensional technique in 20 volunteers. ADC values ranged from 1.79 +/- .39 to 2.95 +/- .58 (x10(-3)mm(2)/sec), re latively high but similar to other reports, Further investigation may help clarify this data, and determine whether the findings result from diffusion properties (and/or radially oriented parenchymal architectu re), or artifacts due to factors such as bulk motion.
