Does high field MRI allow an earlier diagnosis of multiple sclerosis?
Although high field MRI shows a higher detection rate of inflammatory brain lesion in CIS and MS patients with an influence according to MRI criteria, this influence does not lead to an earlier diagnosis of lesion dissemination in time and therefore definite MS.
Long-term estimates of the NNS and the additional NNT are an order of magnitude lower than the short-term estimates published with the results of the ERSPC trial and may be consistent with cost-effective PSA screening in the general U.S. population.
