Reduced Distortion in DWI Through µs-Resolution B-Field Measurement by NeuroCam [Presidential Award Proceedings]
A field probe-equipped coil array (NeuroCam) was employed to perform dynamic, higher-order B-field-based distortion correction (DBFdc) during 12-axis DTI of ten healthy volunteers. Results obtained with and without DBFdc were compared in terms of (i) geometric congruence among the 12 axes’ diffusion-weighted images ; (ii) diffusion parameter (FA, MD, AD, RD) means within white-matter ROIs, and (iii) reproducibility of FA, MD, AD and RD means between 2 scans.
