Researchers have adapted the MedSAM foundation model for multi-class brain tissue segmentation, specifically distinguishing between gray matter and white matter in MRI scans. Their approach involves preprocessing MRI data to create labeled slices and then fine-tuning MedSAM's prompt encoder and decoder while keeping the image encoder frozen. This modified model achieved a Dice score of up to 0.8751 on the IXI dataset, demonstrating the potential of foundation models for complex medical image analysis tasks. AI
