Popis: PurposeTo study if glioma grade could be correlated with perfusion CT parameters; permeability surface (PS) and cerebral blood volume (CBV) and if high-grade glioma would show different parameter levels as compared with low-grade glioma.Patients and methodsPerfusion CT (PCT) was conducted for 40 patients with untreated glioma using 64 multidetector-row CT scanner. Perfusion maps of PS and CBV were generated, and these parameters were measured. World Health Organization (WHO) glioma grades were compared with PCT parameters.ResultsThe 40 patients were classified as low-grade glioma group (18 patients) and high-grade glioma group (22patients). There was highly significant difference (P
