In clinically isolated syndromes, the new McDonald criteria for multiple sclerosis diagnosis require new gadolinium-enhancing lesions for dissemination in time at a 3-month follow-up magnetic resonance imaging scan.

In a cohort of 56 patients, these criteria were specific (95%) but less sensitive (58%) for clinically definite multiple sclerosis at 3 years.

If new T2 lesions were allowed as an alternative for dissemination in time, sensitivity increased (74%) with maintained specificity (92%), enabling an accurate diagnosis of multiple sclerosis in more patients.
