175 MR images of 350 lower legs from 93 subjects (47 healthy, 35 DM1, 6 Pre-DM1, 5 JDM). MR image size was 512×512×30, voxel size 0.7×0.7×7 mm, acquisition used the first echo of a 3 point Dixon gradient echo sequence, TR = 150 ms, TE=3.5 ms, FOV=36 cm, bandwidth 224 Hz/pixel, scan time 156s.
Human subject research approved by the University of Iowa IRB as part of NIH project R01-NS094387.
