Advanced MRI prediction of meningioma histopathological classification: a literature review and case presentations

Meningioma is not uncommon case; however, the differentiation of high-grade from low-grade meningioma important. The rate recurrence grade I 7-20%, but in II 30-40% and III 50-80%. Non-invasive MRI techniques that can differentiate meningiomas before surgery are useful for surgical planning subsequent treatment. We present a review article some case studies (WHO I) III) with conventional continue advanced MRI; we performed diffusion weighted imaging (DWI) apparent coefficient (ADC) value, dynamic susceptibility contrast (DSC), contrast-enhanced (DCE) magnetic resonance (MR) perfusion 3D ASL. From these three cases show ADC DSC, DCE, arterial spin-labelling (ASL) an essential sequence to meningioma.
