Cardiovascular angiography

Cardiovascular angiography is a method of rapidly injecting a contrast agent into a heart cavity or blood vessel through a cardiac catheter, so that the heart and blood vessel cavity are developed under X-ray irradiation. The imaging process is photographed, and the sequence of blood flow containing the contrast agent and the filling of the blood vessels in the heart can be seen from the results of the development, so as to understand the physiological and anatomical changes of the heart and blood vessels. It is a valuable method for diagnosing cardiovascular diseases.
