MRI Radiomics with Habitat Analysis Distinguishes Meningioma Subtypes Preoperatively

Combining T1 contrast-enhanced and T2-weighted MRI radiomics with habitat analysis achieved AUC 0.863 (95% CI 0.763-0.954) for meningioma subtyping, outperforming radiomics-only and habitat-only models.

• In the test set, the combined model achieved an accuracy of 0.716.
• Unimodal radiomics and habitat-only models had lower AUCs (0.770 and 0.619, respectively).
• Habitat analysis identified distinct imaging subregions matching histological features.
