Cardiac coro 心導管檢查 

A coronary angiogram is a test that uses X-rays to look at the heart's blood vessels, called the coronary arteries. It's usually done to see if a blood vessel is narrowed or blocked. A coronary angiogram is most often used to diagnose coronary artery disease.

Sometimes, a computerized tomography (CT) machine is used to look at the heart's blood vessels. This type of angiogram doesn't need tubes placed inside the body. It's called a coronary CT angiogram (CCTA).
