Li X, et al. - In predicting histologic grades of cerebral gliomas, researchers evaluated the diagnostic performance of inflow-based vascular-space-occupancy (iVASO) MRI [a noninvasive perfusion technique that does not require exogenous contrast agents administration] implemented at 3T. For statistical analysis, Kruskal–Wallis test, Mann–Whitney test, and receiver operating characteristics (ROC) curve were used. According to this retrospective study, iVASO MRI could be used to help determine and predict glioma grade.
