FIG 7. Single voxel MR spectrum recorded from a hypothalamic hamartoma showing (from left to right) signal intensity from myoinositol (mI, elevated), total choline (Cho), creatine/phosphocreatine (Cr), and N-acetylaspartate (NAA, reduced) content. The spectrum was recorded from a 4-cm3 region tailored to the hypothalamic hamartomas by using a point-resolved spectroscopy sequence with 3000/30 (TR/TE). The solid line overlaid on the spectrum shows the fitted spectrum produced by LCModel (24), and the upper panel shows the residual of the fit.
