Angiogram, also called Coronary Angiography, is a technique that uses medical imaging to view the organs and blood vessels of the patient’s body. This is particularly performed to view the veins, arteries, and heart chambers to diagnose blockages and other problems.
Angiogram is a medical test done using an imaging technology, typically x-ray based technique.
Angiography is a technique that uses medical imaging to view the organs and blood vessels of the patient’s body. This is particularly performed to view the veins, arteries, and heart chambers to diagnose blockages and other problems. It is done by using an X-Ray based technique, like fluoroscopy (Immediately obtains moving pictures using X-Ray).
A contrast agent like a special dye is injected in the blood stream via a catheter (thin plastic tube), which highlights the blood vessels.The blood vessels materialize in white on the angiogram as they move. Then a few X-Rays are taken and studied.
Coronary Angiography is a procedure, which is done to examine the coronary arteries of the patient’s heart. It is one of the most common types of angiogramperformed.Exceptionally fastscanners are used to obtain images in this test. Before the test is performed, local anaesthesia is given to the patient and a catheter is passed through an artery in the arm or groin, which is then infused with a contrast agent. Post this, X-Ray images are taken out, which gives a thorough view of the blood vessels innards.
Coronary angiography is of two types:
1. Catheter coronary angiography – In this procedure, a catheter is guided into your artery in your arm or groin. The catheter is moved towards the opening of your coronary arteries, and then injected with a contrast agent. Then, X-Rays of the blood vessels are taken.
2. Noninvasive coronary angiography – In this procedure a catheter is not used, instead imaging tests like an ultrasound or MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) are done to take an X-Ray of the blood vessels. Unlike ultrasound and MRI, the patient is exposed to radiation in a CT scan.
