Abstract
P-31 MRS examinations of the brain of 10 healthy volunteers were perfo rmed to determine T2 of the coupled ATP signals by use of the localize d 90-degrees - TE/2 - 2662BAR - TE/2 - acq frequency selective spin ec ho sequence for elimination of phase and intensity distortions. The T2 relaxation times obtained are much longer than usually assumed: gamma -ATP: 89 +/- 9 ms; alpha-ATP: 84 +/- 6 ms; beta-ATP: 62 +/- 3 ms.
