Coronary angiography:

Coronary angiography, which can be done during cardiac catheterization, is a type of medical imaging that uses x-rays and a contrast agent to produce images of blood vessels that feed the heart (coronary arteries). Coronary Angiogram What is a Coronary Angiogram? A Coronary Angiogram or Coronary Angiography is a technique that uses contrast dye and X-ray images to see your heart’s blood vessels, which are called the coronary arteries. It is performed to detect blockage in the coronary arteries. A coronary angiogram is a specialized imaging test that uses X-rays to visualize the blood vessels of the heart. It is a crucial diagnostic tool for detecting blockages, narrowing, or abnormalities in the coronary arteries, which supply oxygen-rich blood to the heart. It is also called a coronary angiogram, cardiac catheterisation, or an invasive coronary angiogram. Coronary angiography involves injecting dye into the coronary arteries.
