X-ray or Radiography
X-rays produce an image that shows internal structures in shades of gray, black and white. X-ray machines are very versatile and can be maneuvered to take pictures from various angles. You may stand, sit in a chair or lie on a table, depending on the part of your body being viewed.
Some types of X-rays work better with a contrast medium (dye) that provides a more detailed image. For this type of exam, you may be asked to take a substance, such as iodine or barium, by mouth or as an enema. X-rays typically take about 15 minutes to perform, but the exam may take longer if a contrast medium is used.
Doctors use X-rays to check for:
- Broken bones.
- Problems in the digestive tract.
- Lung conditions, such as pneumonia.
- Breast cancer and other breast conditions.
X-rays use only a small amount of radiation. However, your technologist may ask you to wear a lead apron to protect certain parts of your body during the exam. Please notify your technologist before X-rays are taken if there’s a chance you may be pregnant.
