Angiography is an examination procedure using X-rays (X-rays) to look at arteries and veins. Angiography helps the doctor determine the level of damage and damage to blood vessels. The examination is generally carried out on patients who have blocked arteries such as coronary heart disease. In an angiography procedure, the doctor injects a dye (contrast) into a blood vessel. With this substance, blood flow can be clearly seen by X-rays. The results of the angiography imaging will be printed in the form of X-rays and stored in a computer file. Based on the area of the blood vessel examined, angiography is divided into several types, namely: Coronary angiography, to examine coronary arteries in the heart. Cerebral angiography, to examine blood vessels in the brain. Renal angiography, to check blood vessels in the kidneys. Pulmonary angiography, to examine the blood vessels in the lungs. Fluorescein angiography, to examine blood vessels in the eye. Extremity angiography,
