Habitat MRI Radiomics Predicts Breast-Conserving Surgery After Neoadjuvant Chemotherapy

A combined habitat MRI radiomics and clinical model predicted feasibility of breast-conserving surgery after neoadjuvant chemo with AUCs of 0.910 (training), 0.839 (internal validation), and 0.755 (external validation).

• Combined model AUCs: 0.910, 0.839, and 0.755 in training, internal, and external validation cohorts.
• Habitat radiomics model alone had AUC 0.886 in training, declining to 0.725 externally.
• Retrospective multicenter study of 315 patients with breast cancer undergoing neoadjuvant chemotherapy.
