From the abstract
A 60-year-old patient with right temporal glioblastoma (WHO CNS grade 4) underwent resection and chemoradiation. Seven-month follow-up MRI showed new contrast enhancement at the resection margin. To distinguish tumor recurrence from treatment-related changes, [18F]FET-PET/MRI was performed.
