What to Expect
Prior to Test
Before your x-ray is taken, you may be asked to remove jewelry and put on a hospital gown.
Let your doctor know if you are pregnant.
Description of Test
A lead shield may be placed on parts of your body not being x-rayed. This will help to reduce your exposure to radiation. You will be placed against a device that holds the x-ray film, or you may be asked to hold a cassette against your body.
The x-ray device will be placed over the part of your body being studied. You will be asked to remain as still as possible while the images are captured.
Once the x-ray is complete, you will be able to resume your daily activities.
