We purpose to test the performance of glioblastoma grading using several perfusion parameters: QTM velocity U, volume transfer constant Ktrans, and blood volume fraction Ve. For Ktrans and Ve calculated using extended Toft’s model, two arterial input function are used: one sampled from Carotid artery and one sampled from the feeding artery near the tumor. The result shows that U has the best classification accuracy comparing with other parameters.
