What is a diagnostic X-ray and how does it work?

X-rays are used to diagnose a wide range of illnesses and injuries, including broken bones, cancer, blocked arteries, and other abnormalities. Safe, low doses of X-rays pass through the body and produce a black and white image on film, video, or a computer screen. Fluoroscopy, which is performed by a radiologist, uses a continuous low-dose X-ray beam and contrast material that can be inhaled, injected, or taken orally or rectally to highlight the area being examined and create a real-time image on a computer monitor.

What happens during your X-ray?

• A technologist will take you to the exam room, ask you some medical questions, and explain what you can expect during your test.
• Depending on what part of your body is being examined, you may need to remove some of your clothing and put on a gown.
• You will need to remove any metal or plastic from the part of your body being examined.
• The technologist will position you sitting, standing, or lying on the exam table and the X-ray will be conducted.
• If you are having a fluoroscopic exam, you will receive special instructions on how to prepare for the exam and how you will receive the contrast material before your exam.

What happens when your exam is complete?

• You can leave immediately after your X-ray.
• If you had a fluoroscopic exam, drink plenty of fluids, especially water, for the next 24 hours to help flush the contrast material from your body.
• The radiologist will review your X-rays and send the results to your physician. If urgent findings are uncovered, the results will be called into your physician immediately.
