MedGemma 1.5 adds native 3D MRI support

MedGemma is effectively democratizing high-end medical imaging analysis that was previously locked behind proprietary cloud APIs like Med-Gemini. Native 3D support allows the model to analyze data across multiple MRI slices, which is crucial for understanding spatial relationships in neuroimaging. By offering open weights, Google enables local deployment that addresses critical data privacy and HIPAA compliance hurdles in healthcare. While the model's integration with MedSigLIP allows for high-fidelity visual reasoning, the gap between its "clinically acceptable" report rates and professional standards remains a significant hurdle for real-world deployment.
