The aim of this study was to investigate WM integrity and its possible relationship to pain symptoms in women with FM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Nineteen FM patients and 21 age\u2010, sex\u2010, and education\u2010matched healthy control subjects were included in the study and underwent diffusion\u2010weighted imaging.
