WHAT IS FLUOROSCOPY?
Fluoroscopy makes a moving x-ray picture of internal organs. A constant stream of x-rays passes through the patient. This casts shadows of internal organs onto a screen. It is used when doctors need to see internal movement.
WHAT IS FLUOROSCOPY USED FOR?
For many tests, fluoroscopy may be only a brief part of the overall procedure. One use of fluoroscopy is to observe the lungs and diaphragm. The diaphragm is the muscle between the chest and the abdomen. It controls breathing. Fluoroscopy shows whether it moves properly. It can also show various parts of the digestive tract. Barium swallow, upper GI, barium enema, and intravenous pyelogram (IVP) tests all use fluoroscopy.
Frequently fluoroscopy is used to aide in needle placement into joints for administration of local anesthesia or contrast. Finally, it may be used to guide the passage of catheters or other tools through the body.
WHERE IS FLUOROSCOPY OFFERED?
WHAT TO EXPECT
An intravenous (IV) line will be placed in your arm and you will be positioned for the x-ray procedure. A dye or contrast substance may be injected into the IV line in order to better visualize the structure being studied. The procedure room may be darkened, so the technologist or radiologist can see the screen clearly while the x-rays are taken.
