The second film, showing the contrast agent in the left side of the peritoneal cavity. Evidence that the left fallopian tube is really patent. There is also a small amount of contrast agent on the right, most probably originating from the left side of the peritoneal cavity, due to patient movements. This image does not suggest that the right fallopian tube is also patent. The horizontally placed contrast agent in the center of the image represents the contrast agent still left in the uterus.
