Interest of the Early Dynamic F-DOPA PET Examination for Differential Diagnosis Between Recurrence and Radionecrosis of Brain Metastasis

Overview

Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain.
