Figure 4e: GBM in 43-year-old man. Transverse (a) preoperative T2-weighted MR image (3600/96), (b) contrast-enhanced T1-weighted MR image (440/14), and (c) ADC map show ill-defined tumor (arrows in a) in right insulo-opercular region. Irregular enhancing area is noted in center of tumor (arrow in b). Minimum ADC value was 1.07 x 10–3 mm2 · sec–1. (d) Postoperative contrast-enhanced transverse T1-weighted MR image (440/14) shows that most of the tumor, including all enhancing components, was removed. (e) Contrast-enhanced transverse T1-weighted MR image (440/14) 2 years after surgery shows no tumor recurrence.
