Open Access Abstract The pathogenetic role of anticardiolipin antibodies aCLs in patients with neuropsychiatric systemic lupus erythematosus NPSLE without cerebral infarcts remains elusive. Magnetization transfer imaging MTI has proved to be a sensitive tool for detecting diffuse microscopic brain damage in NPSLE patients. In this study we examined the correlation between grey and white matter magnetization transfer ratio MTR parameters and the presence of IgM and IgG aCLs and lupus anticoagulant in 18 patients with systemic lupus erythematosus and a history of NPSLE but without cerebral infarcts on conventional magnetic resonance imaging. Lower grey matter mean MTR P white matter mean MTR P white matter peak location P and grey
