Figure 1From: 147 31P Cardiac spectroscopy at 3 T: T1 quantificationA custom coil and protocol for human cardiac 3 T 31P MRS is used to measure the T1s of PCr and -ATP in the human heart via saturation recovery, and a new, efficient dual-TR approach that reduces bandwidth and power requirements. Left, end-systolic time-frame cardiac image showing coil center and 1DCSI slice locations. Right: Cardiac 31P Spectrum (slice 7; TR = 12 s; 10 Hz filter; 13 min).Back to article page
