[New MRI guidelines for multiple sclerosis].

Background: To improve the efficient use of magnetic resonance imaging (MRI) in routine clinical practice, an expert panel has revised the guidelines for its use in the diagnosis and monitoring of multiple sclerosis (MS).

Objectives: The revised guidelines now take into account new developments and relevant advances in knowledge, such as the ongoing debate about safety related to intravenous gadolinium-based contrast agents. The value of spinal cord MRI for diagnostic, prognostic, and surveillance purposes has been re-evaluated. Standardization of brain and spinal cord MRI protocols for diagnosis, assessment of prognosis, and monitoring of therapy, as well as the use of 3D-FLAIR (three-dimensional fluid-attenuated inversion recovery) as the most important sequence in the diagnosis of lesions in the brain have been included, as this allows better interpretation and comparability, e.g., in follow-up assessments.
