A form of X-ray, Fluoroscopy uses a contrast agent like barium or iodine to show the movement of body parts, such as digestive, respiratory or joints. Contrast agents can be given through injection, swallowing or enema, depending on the area being scanned. Fluoroscopy is often used in conjunction with other diagnostic procedures.
Fluoroscopy is a form of an imaging technique to create X-rays (which is a form of ionizing radiation) to produce a series of continuous and real-time moving images of the patient’s internal structures. The procedure primarily consists of a separate X-ray source and fluorescent screen that patients would be placed between and are able to vary the amount of radiation exposure to the patient.
Depending on the purpose, fluoroscopy studies can take as little as 30 minutes to as long as one to three hours.
