Figure 1 Spin-echo magnetic resonance imaging (A) and point-resolved spectroscopy spectrum (B) in a 2 x 2 x 2-cm voxel in an intraventricular septum (white box) of a 66-year-old healthy woman as a normal (NML) volunteer. Total creatine resonance at 3.0 ppm (arrow). The creatine concentration is 25.0 µmol/g wet weight. Lipid resonance at 0.9 to 1.4 ppm.
