This study aimed to demonstrate the feasibility of DTI of the kidney with respiration-triggered acquisition or multiple breath-holding and to explore the best imaging parameters for cortex-medulla differentiation on FA(fraction anisotropy) map. DTI of the rt. kidney from healthy volunteer were analyzed (n=6). 6 different sequences with different acquisition technique, slice thickness, number of signal averaging, and b values were compared. DTI of the kidney with respiration-triggered acquisition was feasible with excellent cortex-medulla differentiation. 3-mm thickness, 3 averages, with b = 0, 200 or 400 produce the best images. Images with multiple breath holding resulted in poor quality.
