文摘

Prediction of malignancy in meningiomas is important for surgery and routine visit. IVIM parameters were useful than ADC values in grade differentiation of meningiomas and correlated with ki-67 index. D value could distinguish tumour grades by 0.479 × 10− 3 mm2/s. Secretory and angiomatous meningiomas had higher DWI and IVIM parameters. Fibrous meningiomas could be distinguished from other subgroups by D*.
