MRI is an important tool in the diagnosis of CNS infections. It allows for identifying various infectious patterns, differentiates them from vascular pathologies or neoplasms, may raise suspicion about a specific pathogen agent and plays an important role in monitoring response to treatment. Recent advances in MRI (e.g., diffusion-weighted imaging and diffusion-tensor imaging, MR spectroscopy, susceptibility-weighted imaging and perfusion-weighted imaging) may further improve the specificity of the MR findings.
