Suh CH, et al. - A literature search of Ovid MEDLINE and EMBASE was conducted up to November 10, 2017 to assess the diagnostic value of diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) for differentiating high-grade glioma from solitary brain metastasis through a systematic review and meta-analysis. Researchers chose studies assessing the diagnostic ability of DWI and DTI for telling high-grade glioma from solitary brain metastasis. In this analysis, 14 studies with 1,143 subjects were involved. According to the findings obtained, DWI, as well as DTI showed a moderate diagnostic value for differentiating high-grade glioma from solitary brain metastasis.
