Fig. 2

Representative spectra from a voxel placed in the left ventricular septal wall of (A) a creatine transporter overexpressing mouse and (B) a double transgenic mouse, with corresponding short-axis scout images showing voxel position (magenta square). Spectra show peaks for 2,3-diphosphoglycerate ([2, 3]-DPG), phosphocreatine (PCr) and the γ, α, and β phosphoryl groups of adenosine-triphosphate (ATP). A 5 mm scalebar is shown for reference
