Normal healthy volunteers (n=10; 5m, 5f) were scanned in both the prone and supine position using a 1.5 T clinical MRI scanner. 31P spectra were acquired using ECG-gated chemical shift imaging (CSI) and peaks were quantified using AMARES fitting. No significant differences in SNR, PCr/ATP ratio, voxel to coil distance, or scan duration were found between the scans performed in the prone and supine position. These results show that supine subject positioning gives may give adequate signal for clinical cardiac spectroscopy, although further work is needed to look at possible increase in breathing motion.
