The uterus is filled with iodine containing contrast media that is radio opaque, and obtaining x-rays as the dye outlines the shape of the uterus is seen. Also the length of the fallopian tubes is noted. This is followed usually by the spillage of dye from the fallopian tubes this indicates patency of the tubes.
