• Fluoroscopy

    Patient undergoing fluoroscopic exam at Lahey ClinicFluoroscopy is a technique used to capture X-ray images in motion. During a fluoroscopic procedure, a radiologist transmits a low energy X-ray beam (lower energy than traditional X-rays) through the patient onto a fluorescent plate outside of the patient. The fluorescent plate is connected to an image intensifier that is in turn connected to a video screen. The resulting image projected on the video screen is a live X-ray movie of internal organs in motion in a specific region of the body. Contrast material is usually administered into the organ system being studied to further delineate structure and aid in diagnosis. For example, barium is utilized to visualize the gastrointestinal track (Upper GI, Barium Enema) and water-soluble contrast is used to visualize the genitourinary system (Voiding Cystourethrogram, Cystogram, Retrograde Urethrogram) as well as bony joints (Arthrogram). Fluoroscopy is also frequently used to guide accurate placement of diagnostic and therapeutic instruments such as catheters into arteries (Interventional Radiology) and feeding tubes into the small bowel.

    Fluoroscopy is used while performing the following examinations:

    Gastrointestinal Studies

    Genitourinary Studies

    • Cystogram/Voiding Cysto Urethrogram (VCUG)
    • Retrograde Urethrogram (RUG)
    • Hysterosalpingogram


    Fluoroscopy is also used in the subspecialties of Interventional Radiology, Neuroradiology, Interventional Neuroradiology, and Cardiovascular Services.
