Which procedure is used to visualize coronary vessels using contrast medium?

Coronary angiography is the procedure specifically designed for visualizing the coronary vessels using a contrast medium. This technique involves injecting a radiopaque dye into the coronary arteries, which can then be visualized through X-ray imaging. It allows healthcare providers to assess the patency of the arteries, identify any blockages or narrowing, and evaluate overall heart health. The use of contrast enhances the visibility of the blood vessels, making it possible to obtain detailed images that are crucial for diagnosing conditions such as coronary artery disease. Other imaging techniques like echocardiograms and CT scans are useful for different evaluations but do not provide the same direct visualization of coronary arteries with contrast as coronary angiography does.
