Summary

During gamma scalpel treatment of brain tumors and metastases, a follow-up magnetic resonance imaging (MRI) scan is performed. The radiologist who reviews the MRI assesses whether there is an increase in signal at the tumor site. This increase potentially indicates that the treatment was not effective. However, in 25% of cases (one in four people), this signal enhancement is not due to ineffective treatment, but to inflammation (swelling/damage) and tissue death around the tumor. This is why when an increase in signal is detected, additional follow-up is essential. The standard additional follow-up has an accuracy of about 83%. This is an observational study on patients with brain metastatis comparing MRI alone or combined to PET-FET to improve accuracy of diagnosis of metastasis recurrence.
