The
proposed fat-insensitive T2water measurement, based on Dixon TSE
with effective TE increments, is accurate over a range of T2 and fat
fraction values and could provide a quantitative alternative to the widely-used
STIR sequence for imaging inflamed and/or oedematous bone and soft tissue.

MRS for FFs of 0, 30 and 40% and agar concentrations of 2% (blue), 3% (green)
