Fluoroscopy is a technique for obtaining X-ray images of internal organs in motion. It projects radiographic images in a movie-like sequence to a monitor. A continuous X-ray beam is passed through the body part being examined and is transmitted to a monitor so the body part and its motion can be seen in detail.
Fluoroscopy enables physicians to look at many body systems, including the skeletal, digestive, urinary, respiratory and reproductive systems. It's used to evaluate body areas including bones, muscles and joints, as well as solid organs like the heart, lungs or kidneys.
Fluoroscopy is used in many types of examinations and procedures like barium X-rays, cardiac catheterization, arthrography (visualization of a joint or joints), lumbar puncture, placement of intravenous (IV) catheters, intravenous pyelogram, hysterosalpingogram and biopsies.
