3D MRI segmentation framework reveals distinct optimization needs for 2D vs 3D models

Researchers have developed a novel weakly supervised learning framework for segmenting 3D MRI data, addressing the challenge of limited volumetric annotations. Their study reveals that techniques beneficial for 2D models, such as strong spatial augmentation and soft-labeling, can degrade performance when applied to 3D counterparts trained on pseudo-labels. Additionally, human-centric preprocessing like contrast enhancement can negatively impact 3D model accuracy by disrupting global statistical cues. AI
