Fluoroscopy is a medical imaging technique that allows radiologists and clinicians to observe what’s happening inside the body in real time. Think of it like an X-ray, but instead of a still image, fluoroscopy provides a moving video with contrast — offering dynamic insight into bodily functions.

This technology is a powerful tool used in both diagnostic testing and medical procedures. Its applications are wide-ranging and impactful.

Kelly Shupp, radiology supervisor at Lehigh Valley Hospital (LVH)–Carbon, is excited to bring this advanced imaging closer to home for residents of Carbon County. She explains how fluoroscopy works and highlights some of the common procedures it supports.

“Fluoroscopy is noninvasive and offers a real-time X-ray administered by a radiologist or physician assistant,” Shupp says. “We can observe internal structures as they function, and when using a contrast agent, we can track how it moves through the body.”

Contrast agents — such as barium or iodine — are either swallowed or injected. Watching these agents travel through the body helps clinicians detect ulcers, abscesses, blockages and other abnormalities.

“Some of the most common diagnostic uses involve the gastrointestinal tract, including the esophagus, stomach and intestines,” Shupp says. “We look for signs of reflux, inflammation, Crohn’s disease and other conditions.”

What to expect during

a fluoroscopy

Preparation for fluoroscopy depends on the specific exam ordered.

You may be asked to avoid eating or drinking for several hours beforehand, and certain medications might need to be paused. Your clinician will provide detailed instructions.

If a contrast agent is used, it will be either injected or swallowed. Most fluoroscopy exams do not require anesthesia. As with standard X-rays, you’ll be asked to remove any metal jewelry.

The procedure typically lasts 30-60 minutes, and there’s no recovery time needed afterward.

Additional uses of fluoroscopy

Fluoroscopy is also used to guide the placement of medical devices or confirm their positioning.

For example, it can verify the location of tubes or assist in accurately placing a needle.

“There are hundreds of different exams we can perform using fluoroscopy,” Shupp says. “We can examine kidney tubes, assess the bladder, monitor postoperative healing and much more.”
