31 P transverse relaxation times of ATP in human brain in vivo

31 P MRS examinations of the brain of 10 healthy volunteers were performed to determine T 2 of the coupled ATP signals by use of the localized 90° ‐ TE /2 ‐ 2662 ‐ TE /2 ‐ acq frequency selective spin echo sequence for elimination of phase and intensity distortions. The T 2 relaxation times obtained...

Zusammenfassung:31 P MRS examinations of the brain of 10 healthy volunteers were performed to determine T 2 of the coupled ATP signals by use of the localized 90° ‐ TE /2 ‐ 2662 ‐ TE /2 ‐ acq frequency selective spin echo sequence for elimination of phase and intensity distortions. The T 2 relaxation times obtained are much longer than usually assumed: γ‐ATP: 89 ± 9 ms; α‐ATP: 84 ± 6 ms; β‐ATP: 62 ± 3 ms.
