ON THE COVER

In this glioblastoma patient, the gadolinium-enhanced T1-weighted MR image showed irregular nodular enhancement suggestive of recurrent disease. Intense activity on 18F-DOPA PET at the site of suspected recurrence increased the suspicion from moderate to high. Accordingly, patient management was changed from wait and watch to chemotherapy.See page 396.
