GI fluoroscopy is a special type of X-ray exam that allows visualization of the body in real time. Unlike static X-rays, the area of interest can be visualized as it moves. This is particularly useful in assessing dynamic structures, such as the GI tract (esophagus, stomach, and intestine). A contrast agent (barium) is typically used with these fluoroscopy studies. Pain management injections are also often performed with fluoroscopy, ensuring precise placement of cortisone within joints or adjacent soft-tissue structures.
