In this study, a performance of the depth resolved
surface coil MRS (DRESS) sequence was assessed in
exercising gastrocnemius muscle at 7T. Two dynamic
examinations (one non-localized and one DRESS-localized)
were performed and the measured metabolic parameters
were compared. Significantly higher PCr drop and no Pi
split in the DRESS localized spectra point towards good
31
P
signal localization from the gastrocnemius muscle.
