What is this test?

This is a fluoroscopic imaging test performed during catheter-based evaluation. Contrast material is delivered through a catheter that is already in place while X-ray images show selected right femoral artery or venous views.

Why might I need this test?

This test may be used to examine the position and patency of blood vessels, identify narrowing or blockage, assess blood flow, or guide catheter-based treatment. It is commonly performed as part of a larger catheterization procedure.

How is the test performed?

A clinician injects contrast through the existing catheter while a fluoroscopy unit takes real-time X-ray images. The images are reviewed to assess the vessels, contrast flow, and the position of the catheter.

How do I prepare for the test?

If this imaging is part of a catheterization procedure, follow the instructions provided by the catheterization team. Tell the team about any contrast allergy, kidney disease, or pregnancy before receiving contrast; no separate fasting is usually required for the imaging itself.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate narrowing, blockage, leakage, abnormal blood flow, or an unintended catheter position. The images are interpreted together with the rest of the catheterization study and your medical history.

Short name

Catheter-based contrast fluoroscopy

Frequently asked questions

Why is contrast used?
Contrast makes the blood vessels and the movement of blood more visible on X-ray images. This helps the clinician evaluate vessel anatomy and flow.
Does the test require a new catheter?
The name indicates that contrast is given through a catheter that is already in place. A separate catheter may still be needed for other parts of the overall procedure.
What should I tell the care team before the test?
Tell the care team about prior contrast reactions, kidney problems, or any allergy to contrast ingredients. Also mention pregnancy if it is possible.
