Multiparametric MRI Habitat Imaging for Preoperative Assessment of Ki-67 Proliferation Index in Meningiomas: A Multicenter Study.
BACKGROUND Preoperative assessment of meningioma proliferative activity relies on the postoperative Ki-67. Habitat imaging captures proliferative variation invisible to whole-tumor analysis by segmenting tumors into distinct subregions. PURPOSE To develop and validate a multiparametric MRI habitat imaging model for p...
