Role of perfusion CT in differentiating between various cerebral masses using normalized permeability surface area product and cerebral blood volume

ObjectiveThe objective was to assess usefulness of a combined analysis using the perfusion computed tomography parameters permeability surface area product (PS) and cerebral blood volume (CBV) in the differential grouping of various cerebral masses.MethodsThirty patients who had a cerebral mass, confirmed by pathologic verification, were included. We classified PS and CBV results for various cerebral masses by visual as well as semiquantitative assessment. To verify statistically significant differences between the groups, one-way analysis of variance was performed.ResultsPatients were categorized into five groups with statistically significant differences (P<.01).ConclusionsPS and CBV were useful in the differential diagnosis of cerebral masses.
