Magnetic Resonance Imaging(MRI) with contrast dyes is a preferred method for finding abnormalities in the Thoracic Aorta. MRI is used for diagnosing Thoracic Aortic Aneurysms or dilations in the heart.
What Is MRI Of Thoracic Aorta With Contrast?
MRI is an imaging test effective in probing Thoracic Aortic Aneurysms along with their size and location.
Radiologists administer contrast media like dyes into blood vessels during this test to get better images of the Thoracic Aorta. Such contrast MRIs are a great alternative to Computerized Tomography(CT) scans for patients who require frequent monitoring. This test is recommended for patients whose first-degree relative has Marfan syndrome or conditions that could cause Thoracic Aortic enlargement. Genetic tests may be needed for those with a family history of Thoracic Aortic Aneurysms and looking to start a family.
CT scan is preferred over MRI, however MRI is used extensively due to the absence of ionizing radiation. CT is preferred for acute aortic disease in emergency rooms.
How Is Contrast MRI Of Thoracic Aorta Performed?
An MRI procedure is as follows:
- Contrast media is administered into the blood vessel.
- Patient is made to lie on a table which slides into a magnetic tunnel.
- Patient is instructed about breathing techniques.
- Images are captured during breath holds.
Patients with claustrophobia may feel uneasy during an MRI procedure.
Side Effects/Risks Of Contrast MRI Of Thoracic Aorta
Despite having no ionizing radiations, Contrast MRI has the following risks:
- Inducing claustrophobia in some patients.
- Incompatibility with ferromagnetic implants.
- Potential contrast media toxicity.
Preparation Before Performing Contrast MRI Of Thoracic Aorta
Prior to the MRI procedure you can:
- Follow pre-appointment restrictions like diet.
- Make a note of your symptoms, daily habits and medications.
- Send in your medical reports.
- Take a family member or friend along.
Post-Care After Contrast MRI Of Thoracic Aorta
After your MRI remember to:
- Drink plenty of water.
- Avoid stressful situations.
