Understanding MRI Features of Multiple Sclerosis: Based on the 2017 McDonald Criteria

Abstract

Since the McDonald criteria were first established for the diagnosis of multiple sclerosis (MS) in 2010, the role of MRI has become increasingly important.

In this article, we review the definition of MS lesions, the exact location stated as dissemination in space in the 2017 McDonald criteria, and the new MS-specific MRI features.
