Today we Discuss about CT Coronary Angiography
A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to the heart. A CT coronary angiogram uses a powerful X-ray machine to produce images of the heart and its blood vessels. The test is used to diagnose a variety of heart conditions.

Why it's done
A CT coronary angiogram is mainly used to check for narrowed or blocked arteries in the heart (coronary artery disease). However, it can check for other heart conditions.
A CT coronary angiogram differs from a standard coronary angiogram. The traditional procedure (non-CT angiogram) uses a flexible tube (catheter) threaded through the groin or arm to the heart or coronary arteries. For those with known coronary artery disease, the traditional approach can also be used as treatment.
Risks
A CT coronary angiogram involves exposure to radiation. The amount varies depending on the type of machine used. Women who are pregnant shouldn't have a CT angiogram because of possible harm to an unborn child.
The test may be done using dye (contrast) to help blood vessels show up more clearly on the images. Some people have an allergic reaction to the contrast dye. Talk to your health care provider if you're concerned about having an allergic reaction. If you have a contrast dye allergy, you might be asked to take steroid medication 12 hours before the procedure to reduce the risk of a reaction.
How you prepare
A health care provider likely will give instructions about how to prepare for a CT coronary angiogram. Driving yourself to and from the test should be OK.
Food and medications
Usually, the test requires not eating anything for about four hours before the test. Drinking water is OK. Don't drink caffeinated beverages 12 hours before the test because they can increase the heart rate, making it difficult to get clear pictures of the heart.
Tell your health care provider about the medications that you take. You might be asked not to take a particular medication before the test.
Clothing and personal items
The procedure requires removing jewelry, glasses and clothing above the waist. You'll be asked to change into a hospital gown.
