['The interest in measuring brain perfusion with intravoxel incoherent motion (IVIM) MRI has significantly increased in the last 3\xa0years. Our aim was to evaluate the prognostic value for survival of intravoxel incoherent motion perfusion fraction in patients with gliomas, and compare it to dynamic susceptibility contrast relative cerebral blood volume and apparent diffusion coefficient.', 'Images were acquired in 27\xa0patients with brain gliomas (16\xa0high grades, 11\xa0low grades), before any relevant treatment. Region of maximal perfusion fraction, maximal relative cerebral blood volume, and minimal apparent diffusion coefficient were obtained. The accuracy of all three methods for 2‑year survival prognosis was compared using the area under the receiver operating characteristic curve and Kaplan-Meier survival curves.', 'Death or survival for at least 2\xa0years after imaging could be documented in 22/27\xa0patients. The cutoff values of 0.112 for the perfusion fraction, of 3.01 for the relative cerebral blood volume, and 1033\xa0×\xa010'] Is iVIM perfusion fraction prognostic for survival in brain glioma?
