Diffusion Tensor Imaging (DTI) of the Kidney at 3 Tesla–Feasibility, Protocol Evaluation and Comparison to 1.5 Tesla

Abstract

Diffusion tensor imaging of the kidney at 3T is feasible and yields significantly higher SNR and CNR. FA and ADCs do not significantly differ from 1.5T. Number of b-values influences ADC-values. Acquisitions in 12 directions provide lower cortical FA-values. We recommend a respiratory-triggered protocol because of improved image quality and reproducibility.
