Fig. 1. T2 measurement by SE series of localized 1H spectra in a 29-year-old patient with AN. a) Display of a 10 x 10 x 30-mm voxel of interest in the left femur diaphysis on T2-weighted TSE (2500/120 ms) image before treatment. b) Stacked plot of 1H spectra with increasing echo delays (TE), obtained before treatment (BMI = 13.9 kg/m2). c) Stacked plot of 1H spectra after 3 months of psychosomatic treatment (BMI = 15.4 kg/m2).
