XRAY and Fluoroscopy
General Radiography (XRAY)
An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging. A bone x-ray makes images of any bone in the body, including the hand, wrist, arm, foot, ankle, knee, leg or spine. The chest x-ray is the most commonly performed diagnostic x-ray examination. A chest x-ray makes images of the heart, lungs, airways, blood vessels and the bones of the spine and chest.
General Radiography (Fluoroscopy)
Fluoroscopy makes it possible to see internal organs in motion. When the upper and lower GI tract is coated with barium, the radiologist is able to view and assess the anatomy and function of the right or ascending colon, the transverse colon, the left or descending colon, sigmoid colon and the rectum esophagus, stomach and duodenum.
In addition to drinking barium, some patients are also given baking-soda crystals (similar to Alka-Seltzer®) to further improve the images. This procedure is called an air-contrast or double-contrast upper GI.
