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.

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.

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.

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.

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

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.

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.

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

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.

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

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

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

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.

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.

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.
