Abstract

Magnetic Resonance Imaging (MRI) in meningitis, as with most other forms of intracranial inflammatory or infectious diseases, is a powerful though largely non‐specific diagnostic tool. The technique is used to detect the presence of disease, and also complications related to the primary process, as well as assess for alternative diagnoses. For imaging these patients, a standard imaging protocol is utilized which includes gadolinium‐enhanced sequences. This unit presents a protocol based on diffusion MRI (dMRI), which can be employed if specific clinical situations require further clarification. The parameters given in this unit are derived from experience at 1.5T and may need to be altered slightly depending on the field strength available and the specific equipment manufacturer.
