Reasons for Test
X-rays can be taken of any part of the body. They are especially good for looking at injuries to bones.
X-rays can also be used to:
- Find an infection
- Locate tumors
- Look for fluid in the lungs
- Look for problems in the abdomen
- Diagnose heart and large blood vessel problems
Possible Complications
An x-ray uses radiation to make images. The low levels of radiation from a single x-ray will not effect most people. If you are pregnant or think you may be pregnant talk to your doctor before the x-ray. Radiation may be harmful to developing babies.
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 that are not being x-rayed. This will help reduce your exposure to radiation.
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 taken. The x-ray device will send x-rays through your body. The x-rays will be captured on the other side of your body by a computer or on film.
After Test
You will be able to resume your daily activities after the x-ray is complete.
