Introduction to Fluoroscopy Contrast Dyes

In fluoroscopy, a special dye called contrast media is sometimes used to help create a clearer view of internal structures like blood vessels, organs, the gastrointestinal tract, or joints. This dye helps doctors better distinguish and outline these areas on the imaging screen, making it easier to diagnose or monitor specific conditions.

Depending on the procedure, contrast can be administered in different ways, such as orally, rectally, or through a vein. For more detailed information on contrast, please visit our comprehensive FAQ section on contrast media.

What are the types of contrast used in fluoroscopy?

There are several types of contrast media, each suited to a different method of administration: orally (through your mouth), rectally (through your rectum), or intravenously (through your veins). When contrast is given intravenously, specific preparations may be necessary, like a recent kidney function test, to ensure your kidneys can effectively clear out the contrast from your body afterward.
