Figure 6. An example 1H spectrum, acquired at 3 T, of left basal ganglia of nondisabled control subject, post processed in Linear Combination Model [1–2]. Metabolites included in modeled basis spectra are shown in table on right. Those detected with reasonable confidence are in blue. Percent standard deviation (%SD) indicate Cramer-Rao lower error bounds. Cho = choline, Cr = creatine, NAA = N-acetylaspartate, ppm = parts per million.1. Provencher SW.
