What is an Angiogram?
What is an Angiogram? Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, blood vessels and organs, with special interest in arteries, veins, and heart chambers. This was traditionally done by injecting a radio-opaque contrast to the blood vessels and imaging using X-ray-based techniques such as fluoroscopy.
Here are definition What is an Angiogram: Cardiac CT scan angiography, Cardiac angiography, coronary angiogram, and cerebral angiography
Cardiac CT scan angiography.
Cardiac CT scan angiography or CT coronary Angiogram (CTA) is a procedure for knowing the blockage / obstruction of the heart artery, usually to diagnose coronary artery disease. Patients injected intravenously (IV) with iodine/dye fluid and heart scanned using a high-speed CT scan, a minimum CT scan 64 slice to see a relatively small heart artery and fast moving in high resolution and 3D.
Angiogram CT scan heart is sometimes used in conjunction with a stress test, wherein Angiogram CT scans of the heart more to see the existence of plaque and/or calcium heap, while more stress test to measure cardiac ability.
The results showed that CTAS is superior to Coronary Artery Calcium Score (CACS) on major adverse cardiac events (MACE).

What is Cardiac angiography.
Cardiac angiography is a screening procedure to detect medical disorders that occur in the heart’s blood vessels. This procedure is one of the most common types of cardiac catheterization procedures.
Cardiac angiography or coronary angiography is performed using an X-ray machine and contrast fluid injected into the coronary arteries in the heart through the arm or groin. This procedure is capable of producing a series of images that can indicate the location, severity, and the number of coronary arteries that have obstruction in coronary heart disease.
What is a coronary angiogram?
Coronary angiography is an invasive test used to visualize a heart artery that supplies blood to your heart muscle. This procedure requires the injection of a special color through a catheter (small tube) into a large artery in the fold of the groin or wrist. The catheter is placed in the heart artery gap before the coloring substance is injected.
Procedures and work of coronary angiography.
The procedure of coronary angiography is a method of using X-rays and contrast dyes (usually iodine) to see the image of the vascular tract and detect the location of obstructions in the heart’s blood vessels. This procedure is important to do because for follow-up such as the installation of the rings in the blood vessels, it is necessary to confirm the location of blockage.
A cardiologist will implement the following procedure.
- You will be given a sedative to make you more relaxed, but you will still be awakened because throughout the procedure you should run certain instructions from the doctor such as holding your breath or cough.
- You are taken to the action room and are welcome lying on the operating table.
- The doctor will give medication to make the arms and groin area, as a location to be made holes in the skin, become numb. The location will be the inclusion of a catheter hose into the arteries blood vessels.
- The doctor will insert the catheter into your arteries while taking an X-ray to find out the location of the catheter hose.
- When the catheter hose is already in the desired location, the doctor will insert a special dye fluid so that the vascular tract can be seen in the X-ray picture.
- By looking at the result of X-rays, the doctor will determine the location of blockage.
- If a blockage occurs, then the doctor can continue the procedure to open blood vessels, for example, with the development of a catheter balloon or installation of blood vessel rings.
What is cerebral angiography?
The head and neck angiography is an X-ray test that uses special dyes and fluoroscopy to take pictures of blood flow in the head and neck veins. Cerebral angiograms can be used to see blood vessels or four-vessel study that carries blood to the brain.
