Ultrasonography and X-ray tubography are both better, but they have their own advantages and disadvantages, and you need to choose the appropriate test according to your own condition.
1. Ultrasound tubography: ultrasound tubography is generally free of radiation, and you can get pregnant in the same month, but ultrasound tubography is not as clear as X-ray tubography, and it is not possible to determine which side of the fallopian tube is blocked or not smooth.
2. X-ray: X-ray has certain radiation and is not recommended for pregnancy in the same month. However, X-ray can more clearly determine which side of the fallopian tube is blocked and whether the tube is open or closed, but it is not recommended for people who are allergic to iodine oil.
There are some differences between ultrasonography and X-ray, and each has its own advantages and disadvantages, so it is necessary to choose between them after the doctor’s consultation, taking into account the patient’s own condition.
In addition, either test should be performed 3-7 days after menstruation and without sexual intercourse.
