CT Angiogram of the Aorta & Coronaries in Hyderabad

A CT angiogram of the aorta and coronaries is a diagnostic procedure that uses computed tomography (CT) imaging to visualize the aorta, the primary blood vessel leading from the heart, and the coronary arteries, the vessels supplying blood to the heart muscle itself. This test is a non-invasive way to detect and evaluate various vascular diseases such as atherosclerosis, aneurysms, and dissections.

During a CT angiogram, a contrast dye is injected into the bloodstream to highlight the blood vessels on the imaging results. The CT scanner takes multiple images as the dye travels through the aorta and coronary arteries, creating a comprehensive view of these structures and making it easier for doctors to diagnose potential problems.

Specific Instructions:

Here are some of the specific instructions you need to follow prior to undergoing a CT angiogram of the aorta and coronaries:

• Fasting : It's usually recommended to fast for 4-6 hours before the procedure to ensure that the contrast dye works effectively.

• Allergies : If you have any known allergies, especially to iodine or contrast materials, you should inform your doctor, as this might affect your ability to undergo this test.

• Medications : Inform your doctor about any medications, supplements, or over-the-counter drugs that you are currently taking. Certain drugs can interact with the contrast material used during the procedure.

• Hydration : Unless otherwise instructed, you should stay hydrated before and after the test. Drinking plenty of water helps your body to eliminate the contrast dye more efficiently.

• Pregnancy : If you are pregnant or suspect that you might be, you must inform your doctor. The radiation from the CT scan could potentially harm the fetus.

• Kidney function : If you have kidney disease or a history of kidney problems, tell your doctor. These conditions could affect how your body handles the contrast dye and potentially lead to complications.

What should I expect during a CT angiogram of the aorta and coronaries?

During the procedure, you will lie on a table that slides into the CT scanner. An IV will be inserted into your arm or hand to administer the contrast dye.

Is the procedure painful?

No, the procedure is not painful. You may feel a slight pinch when the IV is inserted, and a warm sensation as the contrast dye is injected.

How long does the test take?

While the scan itself only takes about 15 minutes, the total time for the procedure, including preparation and recovery, is usually about an hour.

What happens after the procedure?

After the scan, you may be observed for a short period to ensure that there are no immediate side effects from the contrast dye. After that, you can usually go home and return to your normal activities.

Who will interpret the results of my CT angiogram?

The images from your CT angiogram will be interpreted by a radiologist, who will then provide a report to your doctor.

What does an abnormal result mean?

Abnormal results could indicate a variety of issues, such as atherosclerosis (hardening of the arteries), aneurysms (bulges in the vessel wall), or dissections (tears in the vessel wall). Your doctor will discuss these findings with you and explain what they mean in the context of your overall health.

How often should I have this test?

The frequency of this test depends on your specific health conditions and your doctor's recommendations. If you have a history of cardiovascular disease or risk factors for heart disease, your doctor may recommend regular CT angiograms to monitor your condition.

Are there any risks or side effects?

Although rare, risks include allergic reactions to the contrast dye, kidney damage (in patients with pre-existing kidney conditions), and exposure to radiation.

Which doctor should I consult if there are abnormal findings?

A consultation with a cardiologist is usually required for abnormal findings on a CT angiogram of the aorta and coronaries.

Are there any factors that can affect the results?

Movement during the scan, obesity, and the presence of metal implants can affect the clarity of the images and the accuracy of the results.

A CT angiogram of the aorta and coronaries provides valuable diagnostic information for a range of cardiovascular conditions. While the procedure carries some risks, in many cases, the benefit of accurate diagnosis and early detection of disease outweighs these risks. As with any medical procedure, it's essential to discuss the benefits and risks with your doctor before deciding on the best course of action.
