Figure 7

In vivo DRAG-EPSI data from a patient with IDH1-mutated grade-II oligodendroglioma (Patient 2), obtained using TE 78 ms PRESS for VOI prescription at 7T. Shown on top of T2w-FLAIR images (left, top) are the positioning of VOI (red line) and FOV (green line). Spectra within VOI are displayed with a yellow box indicating the tumor mass. On the right, representative spectra from tumor (voxels A and C) and contralateral (voxels B and D) are presented with LCModel analysis results. On the left bottom, the TE 13 ms STEAM water map, B1 map and maps of 2HG and 5 other metabolites are shown on top of T2w-FLAIR images.
