LONDON—Evaluation of cortical lesions improves the specificity of the diagnostic criteria for multiple sclerosis (MS), according to research presented at the 32nd Congress of the European Committee for Treatment and Research in MS (ECTRIMS). Assessment of cortical lesions, in concert with current McDonald criteria, also preserved a high level of diagnostic sensitivity and accuracy in a multicentric cohort of patients with clinically isolated syndrome, reported Paolo Preziosa, MD, Neuroimaging Research Unit at the Institute of Experimental Neurology and Division of Neuroscience at San Raffaele Scientific Institute, Vita-Salute San Raffaele University, Milan, Italy, and his research colleagues.
Since the publication of the 2010 revised McDonald criteria, new data regarding the application of MRI for the diagnosis of MS have become available. In a single-center study, adding the assessment of cortical lesions was shown to modify the diagnostic algorithm, resulting in higher specificity.
