Transverse relaxometry at multiple field strengths may provide increased iron specificity using field dependent relaxation increase (FDRI). We compared high field (4.7 T) transverse relaxometry to single and multislice FDRI using 1. 5 T and 4.7 T. Results for iron-rich subcortical grey matter demonstrate the value of high field measurement, with only slight improvement using FDRI.
