Angiography is performed to find out if a person’s coronary arteries are blocked or not. In simple words, angiography test is conducted with the help of X-ray to study lymph vessels and blood vessels. This type of X-ray shows a cardiologist whether the person on whom the test is carried out has narrowed or blocked arteries.

Angiography with non-inconic contrast is the optimal standard used to find out if a person has Coronary Heart Disease (CHD). The entire angiogram procedure is made successful by using actual X-ray image by filling the vessels with contrasting fluid. When the non-ionic contrasting fluid fills the arteries, the X-rays reveals how much of the arteries and what percentage of the arteries are blocked or narrowed.
