FIG 2. MR images of the BTG in patient 1.
Upper and Lower Left, T1-weighted MR images of a large tumoral mass, including both thalami. Lateral ventricles are expanded owing to the obstruction of the interventricular foramen.
Upper Right, T2-weighted MR image in axial orientation shows the tumoral mass infiltrating both thalami and the head of the caudate nucleus. The VOI for the proton MR spectroscopic image was located by using the three orientations and included a large amount of tumoral tissue.
