Topics in Magnetic Resonance Imaging: June 2015 - Volume 24 - Issue 3 - p 137-146 doi: 10.1097/RMR.0000000000000053 Buy Metrics Abstract Magnetic resonance imaging is a powerful, noninvasive imaging technique with exquisite sensitivity to soft tissue composition. Magnetic resonance imaging is primary tool for brain tumor diagnosis, evaluation of drug response assessment, and clinical monitoring of the patient during the course of their disease. The flexibility of magnetic resonance imaging pulse sequence design allows for a variety of image contrasts to be acquired, including information about magnetic resonance–specific tissue characteristics, molecular dynamics, microstructural organization, vascular composition, and biochemical status. The current review highlights recent advancements and novel approaches in MR characterization of brain tumors. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.
