The fluoroscopy also uses X-ray to generate images. However, instead of getting a “picture” with X-ray, fluoroscopy is akin to getting a video with X-ray. Just as in regular video, motions and timed interactions between different entities can be visualized and analyzed. Usually when your doctor asks for a fluoroscopy, he or she is asking for evaluation of the gastrointestinal tract with enteric contrast material. Rarely, they may want to evaluate other motion sensitive abnormalities.
Fluoroscopy is done with the help of a contrast substance. This contrast can be air (taking fizzy tablets to put air in the stomach), contrast material (barium to see the movement of swallowing or the intestines), or water soluble substance containg iodine which is injected in blood vessels to see whether they are narrowed. The radiologist uses fluoroscopy to examine the bladder, uterus, fallopian tube, and the intestine.
The interventional radiologist and cardiologist examine the blood vessels and heart. If there is vascular narrowing, they can use special instruments to dilate the narrowing under fluoroscopic guidance.
Fluoroscopy may be used to guide biopsies or remove fluid from the chest or abdomen. The gastroenterologist uses fluoroscopy to guide his/her catheter into the ducts that bring the digestive juices from the pancreas or liver to the intestines.
During fluoroscopy, the patient is positioned on an examination table, and with the targeted area of the body exposed. A special X-ray scanner captures images of targeted area, including internal vessels and organs. The patient is usually asked to assume different positions during fluoroscopy.
You will not feel any effect from the use of x-rays during the procedure. Every physician has been taught to use the least amount of x-ray necessary to see what he/she needs to see. The use of x-ray imaging by specially trained physicians is tightly controlled. Your safety is our greatest concern.
Plain Fluoroscopy:
Some procedures, such as assessing the movement of joints, require no preparation.
Fluoroscopy with Contrast:
If the procedure is being done under anesthesia,sedation or if the intestines are being examined, you will be asked not to eat for 6-8 hours before. You’ll be asked to remove any clothing, jewelry, or other objects that may interfere with the procedure. You’ll be given a gown to wear.
