Universal Muscle Segmentation Model for MRI Achieves High Dice Score Acros Diverse Anatomy

SegmentAnyMuscle, a universal MRI muscle segmentation model, achieved a mean Dice score of 88.45% on routine sequences and 86.21% in challenging cases across 11 anatomical regions. It correlated with expert measurements (r>0.99).

• Trained on 316 MRI exams from 160 patients covering 11 anatomical regions.
• Performance remained strong in clinical challenging cases including muscular atrophy and implant artifacts.
• Automatic muscle mass measurements correlated near-perfectly with manual assessments (Pearson r>0.99,p<0.001).
