MR Angiogram Arch of Aorta / Thorax

The MR Angiogram of the Arch of the Aorta and Thorax is a non-invasive imaging test that uses magnetic resonance imaging (MRI) to visualize the blood vessels in and around the aorta and the thorax. The aorta is the main artery that carries oxygenated blood from the heart to the rest of the body, and its arch is a curved section near the heart from which major blood vessels arise. The thorax is the part of the body between the neck and the abdomen, containing the heart and lungs.

This test helps in assessing the health of the aorta and surrounding blood vessels. It is crucial for diagnosing and evaluating conditions such as aneurysms, dissections, blockages, or malformations in the blood vessels. The images produced provide detailed information about the blood flow, structure, and integrity of the blood vessels, which helps the doctor make informed decisions regarding the course of treatment.

Specific Instructions:

• Fasting : Usually not required, but follow the doctor’s instructions.

• Medications : Inform your doctor about any medications you are taking.

• Allergies : Inform your doctor of any known allergies, especially to contrast materials.

• Pre-test Precautions : Remove all metallic objects including jewelry, glasses, and hearing aids as the MRI machine uses strong magnets.

• Clothing : Wear loose, comfortable clothing. You might be asked to wear a hospital gown.

• Kidney Function : Inform your doctor if you have kidney problems as the contrast material used could affect kidney function.

What is an MR Angiogram Arch of Aorta / Thorax?

This is a specialized imaging test that uses magnetic resonance imaging (MRI) to obtain detailed images of the blood vessels in and around the arch of the aorta and the thorax.

Why is this test done?

This test is performed to diagnose and evaluate conditions such as aneurysms, blockages, dissections, or malformations in the blood vessels. It helps in planning surgeries or other interventions and monitoring the progress of known conditions.

How is the test performed?

You will lie on a table that slides into the MRI machine. A contrast material may be injected into your vein to improve the clarity of the images. The machine will make loud noises, and you must remain still during the test. The procedure usually takes 45 minutes to an hour.

Is the test painful?

The test itself is not painful, but some people might find it uncomfortable to lie still for an extended period. If you are claustrophobic, inform your doctor, as sedation might be necessary.

Do I need to fast before the test?

Fasting is usually not required, but it is important to follow the instructions given by your doctor.

Is there any risk associated with the MRI?

MRI is generally safe. However, as it uses magnets, it can affect pacemakers, implantable devices, or metal implants. The contrast material used can cause allergies in some individuals or affect those with kidney problems.

What should I do after the test?

There are no specific post-test precautions, but if sedation was used, it’s advised not to drive or operate machinery until the effects wear off. Drinking water can help flush out the contrast material if used.

How long will it take to get the results?

The results are usually available within a few days, but it may vary depending on the facility.

What do the results mean?

The results will show the structure and blood flow of the aorta and surrounding blood vessels. The doctor will interpret the images to diagnose, assess, or rule out any abnormalities or conditions.

Which doctor should I see if my results are abnormal?

If your results are abnormal, you should consult a cardiologist or a vascular surgeon for further evaluation and management.

Can I undergo MRI with a pacemaker?

Some pacemakers are MRI-compatible. However, it's essential to inform your doctor and the radiology team about your pacemaker.

What if I have claustrophobia?

If you have claustrophobia, inform your doctor beforehand as you might need mild sedation or use of an open MRI machine.

Is the contrast material safe?

Contrast materials are generally safe but can cause allergic reactions in some individuals. It's important to inform the doctor if you have had reactions in the past.

How often should this test be done?

The frequency of this test depends on the specific medical condition being monitored. Follow your doctor's advice regarding how often the test should be performed.

Can I take my medications before the test?

Generally, you can take your medications. However, it’s important to inform the doctor about all the medications you are taking.

MR Angiogram of the Arch of the Aorta and Thorax is an essential diagnostic tool that provides valuable information about the blood vessels in the chest area. It’s a safe and non-invasive method, and knowing what to expect can help in being well-prepared for the test. Always follow your doctor’s instructions and communicate any concerns or questions you might have regarding the test.
