New method quantifies uncertainty in 3D medical image segmentation

Researchers have developed a new method called Class-Aware Asymmetric Weighted Conformal Prediction (CA-WCP) to quantify uncertainty in 3D medical image segmentation, particularly for foundation models like MedSAM. This approach addresses limitations of existing methods by accounting for class-specific biases and distribution shifts common in 3D segmentation tasks. CA-WCP provides calibrated uncertainty estimates for each class, demonstrated to reduce interval width while maintaining coverage guarantees on benchmarks like BraTS 2020. The calibrated intervals can also be used to generate uncertainty-conditioned radiology reports by feeding them into multimodal large language models. AI
