Abstract
Renal apparent diffusion coefficients (ADCs) were anisotropic within and significantly different between cortex and medulla using a relatively motion‐insensitive one‐dimensional technique in 20 volunteers. ADC values ranged from 1.79 ±.39 to 2.95 ±.58(× 10‐3mm2/sec), relatively 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 architecture), or artifacts due to factors such as bulk motion.
