Radiopaakse

Radiopaakse refers to the ability of a substance to absorb X-rays, making it visible on a radiograph. The term is derived from the Greek words "radio," meaning ray, and "paaskein," meaning to pass through. In medical imaging, radiopaak substances are used to enhance the visibility of certain structures or tissues on X-ray images. These substances are often contrast agents, such as barium sulfate or iodine-based compounds, which are administered orally or intravenously to improve the contrast between different parts of the body. Radiopaak substances are commonly used in diagnostic procedures to visualize the gastrointestinal tract, urinary tract, and blood vessels. The degree of radiopaakness is typically measured in Hounsfield units (HU) on computed tomography (CT) scans, with higher values indicating greater absorption of X-rays. The use of radiopaak substances is an essential tool in radiology for diagnosing and monitoring various medical conditions.
