Abstract
This work reports the apparent T2 relaxation times of macromolecules measured at 9.4 T in the human brain. The measured T2 times are between 10 and 40ms, with longer relaxation times of around 50 ms for M2 and M3. The J-evolution of the peak at 2.7 ppm is observed at longer echo times. The full-width half-maxima of the simulated peaks are significantly broader than the T2 component of the lineshapes.
