Cholecystography with oral contrast is a specialized radiologic procedure designed to evaluate the gallbladder, an organ situated in the upper right quadrant of the abdomen that plays a crucial role in the digestive process by storing bile. Bile is a digestive fluid produced by the liver that assists in the breakdown of fats. During this procedure, a contrast dye is administered orally to the patient several hours before the examination. This contrast agent is absorbed and subsequently excreted by the liver, accumulating in the gallbladder, which allows for enhanced visualization of the organ on X-ray images. The procedure is conducted using fluoroscopy, a real-time imaging technique, while the patient is positioned supine on the examination table. Radiographic films are captured at specific intervals throughout the procedure to document the findings. The presence of gallstones is indicated by darker areas within the gallbladder or bile ducts on the X-ray images. Additionally, the procedure can reveal other abnormalities such as tumors, polyps, inflammation, infection, and gallbladder dysfunction. To further stimulate the gallbladder's function during the examination, the patient may be provided with a special liquid to encourage the release of bile, enhancing the diagnostic capabilities of the study.
