POSSIBILITIES OF MAGNETIC RESONANCE PERFUSION IN POSTOPERATIVE CONTROL IN PATIENTS OPERATED FOR BRAIN NEOPLASMS

Abstract

The aim of the study is to demonstrate the possibilities of T2*-perfusion in the differential diagnosis of changes in the postoperative zone in patients operated for brain neoplasms. We retrospectively analyzed the data of magnetic resonance imaging using contrast-enhanced MR perfusion, its leading indicator being cerebral blood flow (CBF). As a result of the study, the areas of the increased (corresponding to tumor infiltration) and reduced (corresponding to granulation tissue/ischemic foci) cerebral blood flow were identified which is a determinative differential diagnostic criterion.
