Role of Diffusion Magnetic Resonance Imaging in Assessment of Neoplastic and Inflammatory Brain Lesions

A traditional magnetic resonance imaging (MRI) examination allows us to see a mass lesion and gives us information on its location, homogeneity, and signal strength, as well as the existence of perilesional edema and the degree of contrast enhancement. Differentiating between low and high-grade tumors based on MRI is still problematic in the case of brain mass lesions. The presence of necrotic and/or hemorrhagic regions, substantial vascular edema, significant enhancement, and mass effect all contribute to the heterogeneity of traditional high-grade tumors.
