RöntgenKontrastuntersuchungen

RöntgenKontrastuntersuchungen, also known as contrast-enhanced X-ray examinations, are medical imaging procedures that utilize a contrast medium to improve the visibility of internal body structures during an X-ray. This contrast agent, typically a barium sulfate or iodine-based substance, is administered to the patient through various routes, such as ingestion, injection, or enema, depending on the area of the body being examined.

Once administered, the contrast medium coats or fills the specific organ or vessel, making it appear opaque on the X-ray image. This allows radiologists to better visualize structures that might otherwise be difficult to distinguish from surrounding tissues. Common applications include examinations of the gastrointestinal tract (e.g., barium swallows, barium enemas), urinary tract (e.g., intravenous pyelography), and blood vessels (e.g., angiography).

These investigations play a crucial role in diagnosing a wide range of conditions, including blockages, abnormalities in shape or size, inflammation, tumors, and leaks within organs or vessels. While generally safe, potential risks can include allergic reactions to the contrast agent, particularly iodine-based ones, and in rare cases, complications related to the procedure itself. Patients are typically advised to inform their healthcare provider of any allergies or medical conditions before undergoing a RöntgenKontrastuntersuchung.
