SV-MRS obtained in Volunteer 6 within the left quadriceps muscle.
Voxel size is (20×20×30) mm3, TR=3000ms, TE=135 ms. Note the characteristic spectral signature of normal skeletal muscle containing both Choline (cho) and total Creatine (tCr) peaks, unlike that of musculoskeletal tumors [6]. EMCL and IMCL represent the extramyocellular and intramyocellular lipids.
