Mutlimodality MR imaging for differentiation between brain

BACKGROUND AND PURPOSE: MR perfusion imaging can be used to help predict glial tumor grade and disease progression. Our purpose was to evaluate whether perfusion imaging has a diagnostic or therapeutic impact on clinical management planning in patients with glioma. MATERIALS AND METHODS: Standard MR imaging protocols were interpreted by a group of 3 NRs in consensus, with each case being Perfusion magnetic resonance imaging displays moderate overall accuracy in identifying post-treatment radiation effect and tumor progression in patients with glioma.

Glioma Imaging : Physiologic, Metabolic, and Molecular

review was to investigate if a perfusion MRI examination can distinguish a tumor.

Both strengths and shortcomings of perfusion MR imaging over standard anatomic MR imaging will be discussed as will important pitfalls of the technique. Perfusion weighted imaging is a term used to denote a variety of MRI techniques able to give insights into the perfusion of tissues by blood. There are three techniques in wide use to derive one or more perfusion values: techniques. dynamic susceptibility contrast (DSC) MR perfusion. The main role of perfusion imaging is in evaluation of ischemic conditions (e.g.

Therefore, correlations between MR perfusion parameters and other MR‐independent tumor physiological parameters are analyzed. II. METHODS. Blood perfusion, which is accessible by MR perfusion parameters, is a determinative parameter for oxygenation.
