What Is Fluoroscopy and What Does It Test For?

If your doctor has ordered a fluoroscopy, you might be wondering: What exactly is it? Is it just an X-ray?

Fluoroscopy is an advanced imaging procedure that uses continuous X-ray beams to produce real-time video images of your internal organs, joints, or blood flow. It’s commonly used in both diagnostic tests and image-guided procedures, offering more detail and movement tracking than a standard X-ray.

X-Ray vs. Fluoroscopy: What’s the Difference?

While both fluoroscopy and standard X-rays use radiation to capture images, the key difference is:

• X-ray: Produces a single still image, like a snapshot.
• Fluoroscopy: Produces a live video, allowing doctors to view motion (such as swallowing, blood flow, or joint movement) in real time.

Think of X-ray as a photo—and fluoroscopy as a video stream.

What Is Fluoroscopy Used For?

Fluoroscopy is highly versatile and is used for a variety of purposes, from diagnosing conditions to guiding medical procedures. Some of the most common uses include:

1. Gastrointestinal Exams

Fluoroscopy can help diagnose GI issues like:

• Ulcers
• Tumors
• Leaks or blockages
• Acid reflux
• Swallowing disorders

It’s often combined with a contrast dye (such as barium) to better visualize the esophagus, stomach, and intestines.

2. Arthrography (Joint Imaging)

If you have chronic joint pain or injury, fluoroscopy may be used to assess:

• Knees
• Shoulders
• Elbows
• Hips

A contrast agent may be injected into the joint to better see damage, inflammation, or abnormalities.

3. Blood Flow & Circulation

Fluoroscopy helps evaluate:

• Blocked arteries
• Poor circulation
• Varicose veins

By tracking how contrast dye moves through blood vessels, doctors can pinpoint the location and severity of blood flow issues.

4. Interventional Guidance

Fluoroscopy isn’t just for diagnosis—it’s also used during minimally invasive procedures, such as:

• Catheter placements
• Pain management injections
• Sclerotherapy for varicose veins
• Biopsies

What to Expect During a Fluoroscopy Procedure

Fluoroscopy is usually performed at an outpatient imaging center and is typically quick and painless.

Here’s what you can expect:

• You’ll lie on a table beneath an X-ray machine.
• A contrast dye may be given (or injected) depending on the area being examined.
• The machine will capture moving images while you stay still.
• Most procedures take 15–60 minutes.

‍Note: While fluoroscopy uses radiation, the exposure is minimal and considered safe. However, let your provider know if you are pregnant or may be pregnant.
