English: Sonohysterography taken on a 41 year old woman because of metrorrhagia. The sterile saline instilled into the cavity of the uterus is anechoic (rendered as dark in the middle of the image). It shows a normal endometrium as a hyperechoid (brighter) band around the cavity, in this case without any focal changes. The endometrium is, in turn, surrounded by the uterine wall which stretches almost to the right border of the image. The urinary bladder is visible at bottom right, which is anteriorly in the body.
