Proton spectroscopy of human stroke: assessment of transverse relaxation times and partial volume effects in single volume steam MRS

AM Blamire, GD Graham, DL Rothman… - Magnetic resonance …, 1994 - Elsevier
Proton T 2 relaxation times were measured in 13 stroke patients and 13 aged-matched
normal subjects at 2.1 T. Spectra were acquired from an 8-cc volume using the STEAM
sequence with echo times (TE) of 30.4 ms and 270.0 ms and repetition time of 2.8 s.
Transverse relaxation times were estimated using two-point calculations. Percentage
volume of infarct in the STEAM voxel was measured on spin-echo MRI encompassing the
infarct and correlated with the peak amplitude of N-acetylated compounds (NA). T 2 values …
