JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 683 OP 688 DO 10.1136/jnnp.54.8.683 VO 54 IS 8 A1 D H Miller A1 F Barkhof A1 I Berry A1 L Kappos A1 G Scotti A1 A J Thompson YR 1991 UL http://jnnp.bmj.com/content/54/8/683.abstract AB Serial gadolinium enhanced MRI of the brain detects much clinically silent disease activity in early relapsing-remitting and secondary progressive multiple sclerosis (MS), and thus has an important role in monitoring the effects of therapy. Based on the proceedings of a recent Commission of the European Communities (CEC) workshop and a review of the literature, guidelines are presented for using MRI to monitor treatment trials in MS. The guidelines consider: A) MRI system and techniques; B) patient selection; C) trial design; D) analysis of results. Priorities for future research are also indicated.
