X-ray & Fluoroscopy

What are X-ray and fluoroscopy?

An X-ray captures a still picture of bones and certain tissues using a small dose of radiation. Fluoroscopy is essentially "live X-ray" — moving images that allow your radiologist to watch organs in motion and guide procedures in real time.

What they're used for

X-rays: broken bones, joint problems, lung infections, swallowed objects, abdominal pain, and routine pre-operative chest screening.

Fluoroscopy:

• Swallowing studies (esophagram, modified barium swallow)
• Upper GI series and small bowel follow-through
• Barium enema
• Hysterosalpingogram (fertility evaluation)
• Joint injections
• Image guidance during many interventional procedures

How to prepare

Most X-rays require no preparation — just remove metal items (jewelry, belts, zippers, hairpins) over the area being imaged. You may be asked to change into a gown.

For fluoroscopy involving the GI tract, you may need to fast for 4 to 8 hours and follow specific instructions about water and medications. We'll provide detailed instructions when your exam is scheduled.

Tell us if you might be pregnant.

What to expect during your exam

For X-rays, the technologist will position you standing, sitting, or lying down. They will step out briefly while taking each image. You'll need to hold still and sometimes hold your breath for a moment. Most X-ray exams take 5 to 15 minutes.

Fluoroscopy lasts longer — typically 15 to 60 minutes. For GI studies, you'll drink a chalky-tasting barium contrast (some patients find it easier with flavored options) or receive it through an enema. The radiologist will guide you through breathing and positioning instructions.

Is it safe?

X-rays use ionizing radiation, but a single chest X-ray delivers about the same dose as the natural background radiation you receive in 10 days. We use the lowest dose that produces a diagnostic image.

Pregnant patients should always tell us first — many exams can wait, be done with shielding, or use an alternative imaging method.

After your exam

You can return to normal activities right away. Barium studies may make your stools light-colored for a day or two — this is harmless. Drink fluids to help clear the contrast. Your physician will receive the report from the radiologist, typically the same day.
