You don't have to do anything special to prepare for a chest x ray. However, you may want to wear a shirt that's easy to take off. Before the test, you'll be asked to undress from the waist up and wear a gown.
You also may want to avoid wearing jewelry and other metal objects. You'll be asked to take off any jewelry, eyeglasses, and metal objects that might interfere with the x-ray picture. Let the x-ray technician (a person specially trained to do
x-ray tests) know if you have any body piercings on your chest.
Let your doctor know if you're pregnant or may be pregnant. In general, women should avoid all x-ray tests during pregnancy. Sometimes, though, having an x ray is important to the health of the mother and fetus. If an x ray is needed, the technician will take extra steps to protect the fetus from radiation.
