**Dear @BraTS2024Participants,** We are excited to announce the launch of the **2024 Brain Tumor Segmentation Meningioma Radiotherapy Automated Segmentation Challenge (BraTS-MEN-RT)**. This challenge will utilize a single radiotherapy planning T1c MRI in native resolution with a single expert-annotated radiotherapy target label for both intact and postoperative meningioma cases. You are all invited to download the training data and begin developing automated segmentation models at this time.
