Projectional radiography, X-ray computed tomography and nuclear medicine result in some degree of ionizing radiation exposure but have with a few exceptions much lower radiation doses than what is associated with fetal harm. [1] They are indicated when ultrasonography or MRI is not readily available or not feasible for the diagnostic question ...
A Cochrane review in 2017 found that there was too little evidence to show whether X-ray pelvimetry is beneficial and safe when the baby is in cephalic presentation. [ 3 ] A review in 2003 came to the conclusion that pelvimetry does not change the management of pregnant women, and recommended that all women should be allowed a trial of labor ...
An X-ray film obtained in the AP view of the pelvic inlet and outlet will show a marked gap between the pubic bones. [3] A normal pelvis will show a gap that is 4–5 mm. However, in pregnancy the hormonal influences cause relaxation of the connecting ligaments and the bones separate up to 9 mm. A gap measuring greater than 10 mm indicates a ...

The radioactive gamma rays are emitted through the body as the natural decaying process of these isotopes takes place. The emissions of the gamma rays are captured by detectors that surround the body. This essentially means that the human is now the source of the radioactivity, rather than the medical imaging devices such as X-ray or CT.
Another user raised concern about taking X-rays of a pregnant animal -- but according to a veterinary hospital employee, it is completely safe. "We actually take x-rays of pregnant dogs all the ...
Cancer can also be induced by irradiation, which generally occurs from day 51-280 of pregnancy. [8] Most X-rays occur during the third trimester of pregnancy. [8] There is sparse information on radiation exposure from the first trimester of pregnancy. [8] However, data suggests that the relative risk is 2.7. [8]
