Tubalography patency and patency without patency can be differentiated by how well the contrast material develops in the fallopian tubes and pelvic cavity. Tubalography is mainly done by injecting contrast into the uterine cavity through the cervical opening, and then X-rays are done to observe the patency of the fallopian tubes. During the tubal imaging test, if the X-ray film shows normal shape of the uterine cavity and normal visualization of both fallopian tubes, it means that both fallopian tubes are open. If the X-ray shows that only one fallopian tube is visualized, and the other fallopian tube is not visualized, it means that the other fallopian tube is blocked. If the X-ray shows that the contrast medium is unevenly distributed or slow in developing when it passes through the fallopian tube, it means that the tubes are open but not clear. If you want to judge whether the fallopian tube is open or not open after having a tubal imaging, you need to combine the X-ray with the doctor’s consultation to make a comprehensive judgment.
