A Pilot Study of Insert Nonlinear Diffusion Gradient Coil on Calf Imaging

Motivation: A flexible light-weight nonlinear gradient coil was recently proposed and the feasibility for diffusion imaging is to be studied. Goal(s): To get EPI imaging on calf with the presence of the nonlinear diffusion gradient coil Approach: We design the experiment, processing pipeline, and an ADC map is shown as preliminary quantitative validation. Results: This study demonstrates the feasibility of diffusion imaging using an insert diffusion gradient coil. Impact: This study demonstrates the feasibility of diffusion imaging using an insert diffusion gradient coil, paving the way for further application of muscle and nerve imaging on the lower extremities with high gradient strength.
