Fig. 1E —70-year-old man with histopathologically proven T3a prostate
cancer with prostate-specific antigen level of 10 ng/mL and Gleason score of 6
(3 + 3). Tumor extended over four spectroscopic slices. Patient had total
number of 31 tumor voxels and 7.75 voxels per slice. Note: Endorectal coil is
rotated to left, but tumor is clearly visible because it is located on same
side. Overlaid spectral grid covering tumorous lesion with voxels of nominal
size of 0.45 cm3. Volume of interest (white) is close
around prostate. Voxels covering tumorous lesion have pathologic metabolite
ratio with high choline and low citrate value.
