The assessment perfusion in glioma is an important information in the tumor characterization. Traditional MRI methods employed to analyze glioma are based on the application of contrast agents to enhance the T1 signal and/or to measure perfusion within the tumor cells. The analysis of tumor microvasculature however is hampered by the size of contrast agent molecules. In that sense, SWI can be employed, although it does not provide quantitative information. IVIM maps showed to be an interesting alternative for such assessment, even showing potential of an early biomarker to assess early changes in perfusion, specially in low grade gliomas.
