In the clinical settings it is essential to accurately assess, whether or not a brain metastases has been successfully treated or whether it requires additional treatment, especially in high dose radiation therapy, such as stereotactic radiosurgery (SRS). The present prospective study aims to determine the ability of Diffusion Weighted (DW)- and Dynamic Contrast Enhanced (DCE)-MRI to predict the long-term response of brain metastases within 72 hours of SRS. The preliminary results are promising as it will inform the treating physicians at an early time point about which patients will benefit from SRS (or not).
