MR RATE: A Vision Language Foundation Model and Dataset for Magnetic Resonance Imaging This is the MR RATE nvseg ctmr repository, part of the MR RATE dataset release. It contains multi label segmentations predicted with the NV Segment CTMR model. For full dataset details, native space MRI volumes, radiology reports, metadata, and data splits, please refer to the MR RATE repository. To explore, download, and work with the dataset see Dataset Organization & Getting Started . [2026 04 03] This repository replaces the old Forithmus/MR RATE vista seg repository. Multi Label Segmentations Within each study in native space, a T1 weighted MRI volume is selected as the center modality and all other MRI volumes acquired in the same study are referred to as moving modalities . For center modality volumes, voxel wise anatomical multi label brain segmentations are predicted using the NV Segment CTMR (MRI BRAIN) model. Additionally, for center and moving modality volumes, voxel wise anatomical multi label body segmentations are predicted using the NV Segment CTMR (MRI BODY) model. Goal of sharing these segmentations is supporting region of interest analysis and various downstream tasks. This rep…
