If my dog has a "Liver Shunt." Will you use this?

es! We inject a dye into a vein and watch it travel to the liver. If there is a "shunt" (a vessel bypassing the liver), we see the dye take the wrong exit ramp in real-time.

No. Fluoroscopy units (C-Arms) are expensive and require specialized training and room shielding. It is typically found in specialist centers or advanced general practices like our Ormeau Vet.

What is an Endoscopy?

An Endoscopy puts a camera inside the throat to look at the surface (is it red/ulcerated?)

What is an Fluoroscopy?

A Fluoroscopy looks through the throat to look at the function (are the muscles working?). We often use both Endoscopy and Fluoroscopy to fully understand a swallowing problem.

Fluoroscopy | Ormeau Vet

We often talk about X-rays as “snapshots” of your pet’s health. They are perfect for freezing a moment in time to look at a broken bone or an enlarged heart. But life doesn’t stand still. Sometimes, the problem isn’t the structure of the organ; it’s how the organ moves.

To diagnose these dynamic problems, Ormeau Vet utilizes Fluoroscopy, which is like a “Video X-ray.” Instead of a single static photo, Fluoroscopy gives us a continuous, moving view inside your pet’s body.

What is Fluoroscopy?

Standard Radiography (X-ray) shoots a beam through the body to capture one image on a sensor.

Fluoroscopy sends a continuous, low-dose beam of X-rays through the patient to a screen. It’s like watching a live black-and-white movie of your pet’s skeleton and internal organs.

We typically use a specialized machine called a C-Arm (named because it looks like a giant letter ‘C’). It can rotate around your pet, allowing us to view them from any angle without having to move them while they are asleep.

When Do We Use It?

Fluoroscopy is a specialized tool used for three main scenarios where “movement” is the key to the puzzle.

1. Swallowing Disorders (The “Barium Swallow“)

If your dog regurgitates food instantly after eating, they might have a condition called Megaesophagus or a stricture (narrowing).

The Test: We feed your pet a meal mixed with Barium (a liquid that shows up bright white on X-rays).
The View: Using the fluoroscope, we watch the food travel down the throat in real-time. We can see exactly where it stops, if it flows backward, or if the muscles aren’t pushing properly.

2. The Coughing Dog (Tracheal Collapse)

Small dogs (like Yorkies or Poms) often suffer from a “honking” cough. This is often due to a collapsing windpipe.

The Test: A standard X-ray might catch the windpipe looking normal. But with fluoroscopy, we can watch the windpipe while the dog coughs. We can see the exact moment the walls collapse, confirming the diagnosis.

3. “Keyhole” Orthopedic Surgery

This is the most common use in modern surgery. If we are fixing a broken leg with a metal plate or pin, we need to know the screw is in the perfect spot.

Instead of taking an X-ray, developing it, adjusting the screw, and taking another X-ray (which takes forever), the veterinary surgeon just taps a pedal. The fluoroscope shows the bone live on a screen. We can guide the drill with millimeter precision, making the surgery faster and safer.

What to Expect During the Visit

1. The Contrast

For swallowing or gut studies, we need to make the invisible visible. We will feed your pet a special contrast agent (usually Barium or Iodine). Most dogs actually like the taste!

2. The Setup

For Surgery: Your pet is fully anesthetized.
For Swallowing/Coughing: We often need the pet awake (standing in a special box or restrained gently) because we need them to swallow or cough naturally. If they are asleep, these reflexes stop working.

3. The Safety

Because the X-ray beam is “on” for longer than a normal snapshot, we are very careful with safety. The machine pulses the beam to minimize exposure, and our staff wear specialized heavy lead gowns. The total radiation dose is still very low and considered safe.
