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 Basic to tumor growth in the brain is the recruitment of new vessels, which investigators have attempted to prevent with a plethora of angiogenesis inhibitors provided in phase I/II clinical trials. 1 Similarly, conventional therapies like radiotherapy are at least partly mediated by microvascular damage. 2 Of newer MRI modalities, perfusion MRI has emerged as a unique marker of tumor-induced pounds of masses. The role of the most commonly used advanced MR imaging techniques—perfusion imaging, diffusion-weighted imaging, and MR spectroscopy—in the diagnosis and classification of the most common intraaxial brain tumors in adults is explored. These lesions include primary neoplasms (high- and low-grade), secondary (meta- Brain tumors can bring about the formation of new blood vessels, a process known as angiogenesis.

Purpose This meta-analysis examined roles of several metabolites in differentiating recurrent tumor from necrosis in patients with brain tumors using MR perfusion and spectroscopy. Methods Medline, Cochrane, EMBASE, and Google Scholar were searched for studies using perfusion MRI and/or MR spectroscopy published up to March 4, 2015 which differentiated between recurrent tumor vs. necrosis in
