CE-MR imaging, thallium SPECT, FDG-PET, and ASL-MR images from case 1 (A) with metastatic renal cell carcinoma to periventricular white matter of the posterior left lateral horn. CE-MR imaging shows new enhancement in the region treated. SPECT was positive while PET and ASL were negative for tumor recurrence. Biopsy of the target region indicated radiation necrosis in case 2 (B) with metastatic breast cancer to the right cerebellum. CE-MR imaging shows new enhancement in the region treated. PET (SUV = 6.6) and ASL were positive for tumor recurrence. Biopsy of the target region indicated tumor recurrence in case 3 (C) with metastatic melanoma to the right inferior frontal cortex. Only PET was positive for tumor recurrence (SUV = 10.7). Biopsy of the target region indicated tumor recurrence.
