[Role of perfusion imaging in computed tomography in diagnostics of cerebral gliomas].
CT perfusion is a new diagnostic method which enables imaging of the hemodynamics of tissues and organs. Until now most of the publications have been focused on the use of this technique to assess acute stroke. The aim of the presented work is to show the role of CT perfusion in the diagnosis of cerebral gliomas. These tumors are characterized by intensive vascularity which results in an increased blood volume (CBV), blood flow (CBF) and permeability surface (PS) values in perfusion CT examination. A correlation has been reported between perfusion parameters and the histopathological tumor grade. CT perfusion provides morphological and functional information which is useful in the diagnosis, planning treatment strategies and monitoring of the therapeutic effect in cerebral gliomas.
