The choice of B-ultrasound and X-ray contrast can be voluntarily chosen according to the patient's condition, the patient's mind to ** and radiation, and the advantages and disadvantages of different contrasts. B-ultrasound and X-ray contrast have the same accuracy in determining the patency of the fallopian tubes, and the level of evidence recommended by the guidelines is the same. In addition to judging that the fallopian tubes are patency, other information acquisition has its own advantages.
B-ultrasound imaging: no radiation, the uterine lesions and ovarian lesions can be understood at the same time, which is equivalent to adding a four-dimensional B-ultrasound. The requirements for the operator are high. Access to information is entirely up to the sonographer. The cost is about 400 yuan more expensive than X-ray. Most of the two fallopian tubes cannot be observed at the same time.
X-ray imaging: less cost, good overall view (both fallopian tubes can be observed at the same time), objective images, slightly more understanding of fallopian tubes and pelvic information, contrast film can be read by multiple parties, less affected by the subjective level of the operator. There is a small amount of radiation (a plain chest x-ray: 002msv, the minimum radiation dose of fetal teratogenicity is 50msv, which means that teratogenicity can only be achieved by taking 2500 ordinary chest X-rays in a row). Pregnancy in the following month on x-ray had no clinically confirmed fetal anomaly.
In general:
A plain chest x-ray: 002msv
A knee x-ray: 0005msv, a regular tooth tablet: 001 msv, one head CT: 2 msv
One chest CT: 8 msv
The minimum radiation for teratogenicity is 50 msv, which means that teratogenicity can only be achieved by taking 2500 ordinary chest X-rays in a row). Pregnancy in the following month on x-ray had no clinically confirmed fetal anomaly.
