A CT angiogram is a type of imaging test that uses X-rays and a computer to create detailed pictures of the blood vessels in your body. It is also known as a computed tomography (CT) angiogram or a CT coronary angiogram. This test is used to diagnose and evaluate a variety of conditions, including blockages in the arteries, aneurysms, and other vascular diseases.
What is a CT Coronary Angiogram?
A CT coronary angiogram is a type of CT angiogram that is used to diagnose and evaluate coronary artery disease. It is used to detect blockages in the coronary arteries, which are the blood vessels that supply oxygen-rich blood to the heart.
Why Might I Need a CT Angiogram?
Your doctor may recommend a CT angiogram if you have symptoms of a vascular condition, such as chest pain, shortness of breath, or leg pain. It can also be used to evaluate the results of a traditional angiogram (or cardiac catheterization) or to monitor the progress of a vascular condition.
What is the Difference Between a CT Angiogram and a Traditional Angiogram (or Cardiac Catheterization)?
A traditional angiogram (or cardiac catheterization) is an invasive procedure that involves inserting a thin tube (catheter) into an artery in your arm or leg and then injecting a contrast dye into the artery. The dye helps the doctor see the blood vessels on an X-ray. A CT angiogram is a non-invasive procedure that uses X-rays and a computer to create detailed pictures of the blood vessels.
What is the Difference Between a Cardiac CT Scan and a CT Coronary Angiogram?
A cardiac CT scan is a type of imaging test that uses X-rays and a computer to create detailed pictures of the heart and its blood vessels. A CT coronary angiogram is a type of CT angiogram that is used to diagnose and evaluate coronary artery disease.
Who Performs a CT Angiogram?
A CT angiogram is usually performed by a radiologist, a doctor who specializes in medical imaging.
How Do I Prepare for a CT Angiogram?
Your doctor will give you specific instructions on how to prepare for your CT angiogram. Generally, you will be asked to fast for several hours before the test and to avoid caffeine and other stimulants. You may also be asked to wear a hospital gown and to remove any jewelry or metal objects.
What to Expect on the Day of the CT Angiogram?
On the day of the CT angiogram, you will be asked to lie on a table and the technician will position you so that the area of your body being examined is in the center of the scanner. You may be asked to hold your breath for a few seconds while the scan is being done.
What to Expect During a CT Angiogram?
During the CT angiogram, you may feel a slight pressure as the table moves through the scanner. You may also hear a humming or buzzing sound as the scanner takes pictures. The entire procedure usually takes about 30 minutes.
What to Expect After a CT Angiogram?
After the CT angiogram, you can usually go home and resume your normal activities. You may experience some mild side effects, such as nausea or fatigue, but these should go away within a few hours.
What are the Risks of a CT Angiogram?
CT angiograms are generally safe, but there is a small risk of radiation exposure. There is also a risk of allergic reaction to the contrast dye used in the procedure.
Who Shouldn’t Get a CT Angiogram?
CT angiograms are not recommended for pregnant women or people with certain medical conditions, such as kidney disease. Your doctor will discuss any potential risks with you before the procedure.
When Should I Know the Results of the Test?
Your doctor will discuss the results of the CT angiogram with you. Generally, the results are available within a few days.
