Phosphocreatine changes in skeletal muscle during 2 s duration ankle dorsiflexion contractions were measured by gating phosphorus 2D chemical shift imaging acquisitions to times before and after contractions performed at 15 s intervals. The results demonstrate that spatially-resolved measurements of both contractile PCr utilization and PCr recovery rate in human leg muscles can be accomplished by gated 2D chemical shift imaging at 3 T.
