Is There a Preferred Method for Scoring Activity
of the Spine by Magnetic Resonance Imaging in Ankylosing Spondylitis?
DÉSIRÉE van der HEIJDE, ROBERT LANDEWÉ, KAY-GEERT HERMANN, MARTIN RUDWALEIT, MIKKEL ØSTERGAARD, ANS OOSTVEEN, PHIL O'CONNOR, WALTER P. MAKSYMOWYCH, ROBERT G. LAMBERT, CÉDRIC LUKAS, ANNE GRETHE JURIK, MAARTEN BOERS, XENOFON BARALIAKOS, JÜRGEN BRAUN, for the ASAS/OMERACT MRI in AS Working Group ABSTRACT. This report summarizes the discussion during a module update at OMERACT 8 on scoring methods for activity in the spine on magnetic resonance imaging. The conclusion was that the 3 available scoring methods are all very good with respect to discrimination and feasibility: the Ankylosing Spondylitis spine MRI score for activity (ASspiMRI-a), the Berlin method (a modification of the ASspiMRI-a), and the Spondyloarthritis Research Consortium of Canada Magnetic Resonance Imaging Index for Assessment of Spinal Inflammation in AS (SPARCC). All 3 methods were judged to be similar with respect to responsiveness and discrimination, although the differences in between-reader intraclass correlation coefficients (ICC) were judged to be relevant (the SPARCC method provided consistently higher ICC). The Berlin and SPARCC methods were preferred most frequently. The development of a new method combining the best elements of all methods is an additional possibility.
