ASL perfusion indexes of normal myometrium in the proliferative and secretory phases. Three healthy volunteers who had normal MRI appearances in the uterus and ovaries with regular menstrual cycles were enrolled in this study. ASL perfusion indexes were calculated as (ASL value in uterus—ASL value in iliopsoas/gluteus muscle) and data were normalized with ASL values in background. Data were shown as the mean + S.E.M relative to an adjusted value of 1.0 for the mean value of the proliferative phase. ASL perfusion indexes in the secretory phase were significantly lower than the levels in the proliferative phase (*P < 0.05)
