Water-fat separation in diffusion-weighted MRI using an EPI-IDEAL approach

Research output: Chapter in Book/Report/Conference proceedingMeeting abstract


Effective fat suppression can significantly extend the acquisition time in EPI-based diffusion MRI outside the brain. We present a single-shot diffusion-weighted EPI in combination with IDEAL method for fat-water sepa-ration utilising the inherent signal averaging from the chemical shift encoding. We utilise a B0 map acquired without diffusion weighting to demodulate images at higher b-values before reconstruction to improve the water-fat separation. This technique was tested in phantom and healthy volunteers.
