[Cerebral gliomas: imaging diagnosis and follow-up]

The management of gliomas evolves towards more aggressive strategies with a combination of surgery, radiotherapy and chemotherapy. Follow-up imaging based on morphological MRI, with simple and reproducible protocols, may be associated with functional MRI and spectroscopy. Baseline postsurgical MRI must be performed within the first three days. Follow-up examinations should be done 2 months after radiotherapy and during chemotherapy, usually after each cycle of two or three treatments. Continued follow-up after therapy is recommended to assess response and detect recurrences or therapeutic complications.
