Foundation models such as Segment Anything Model 2 (SAM2) have transformed natural-image and video segmentation, and recent work has begun adapting them to medical imaging. These adaptations, however, are largely general-purpose models that treat MRI as one modality among many; large-scale, MRI-specific modelling and benchmarking remain limited, even though MRI's low soft-tissue contrast leaves many boundaries effectively invisible on individual slices.
The paper presents a scale‑aware 3D deep‑learning framework for detecting brain metastases in multimodal MRI. It trains separate 3D U‑Nets on two spatial fields of view (96³ and 64³ voxels) and fuses their probability maps via weighted late fusion. On a 97‑patient cohort, this cross‑FOV fusion improved lesion‑level precision and F1 while markedly reducing false positives compared to individual models, demonstrating that complementary spatial context enhances detection performance.

arXiv:2505. 17338v3 Announce Type: replace-cross Abstract: Photorealistic volumetric rendering of CT scans greatly benefits clinical workflows, yet neural approaches such as Neural Radiance Fields (NeRF) and 3D Gaussian Splatting (3DGS) require prohibitive per-scan optimization (hours for NeRF, about 30 minutes for 3DGS), making them impractical in clinical settings.
