What is this test?
MRI of the whole aorta—often referred to as Magnetic Resonance Angiography (MRA) of the aorta—is a non-invasive imaging study that captures high-resolution images of the entire length of the aorta, from the aortic root in the chest through the thoracic and abdominal segments, all the way to its bifurcation in the pelvis. It is typically performed using contrast-enhanced sequences to visualize the aortic wall, vessel lumen, and any abnormalities in blood flow.
What is it used for?

• Detecting aortic aneurysms (bulges in the aortic wall) before they rupture
• Diagnosing aortic dissection, a life-threatening condition where the layers of the aorta separate
• Identifying congenital abnormalities, such as coarctation of the aorta
• Evaluating atherosclerotic plaques or vascular calcification
• Monitoring post-surgical repairs such as grafts or stents in patients with known aortic disease
• Screening patients with genetic connective tissue disorders (e.g., Marfan syndrome, Ehlers-Danlos) for vascular complications
• Assessing unexplained chest, back, or abdominal pain that could stem from vascular causes

Who should get this test?

• Individuals with a family history of aortic aneurysm or aortic dissection
• Patients with known or suspected aortic abnormalities, whether congenital or acquired
• Those diagnosed with hypertension and connective tissue disorders like Marfan, Loeys-Dietz, or Turner syndrome
• People with symptoms such as chest or abdominal pain, or who have an aortic bruit on examination
• Patients undergoing surveillance following aortic repair surgery or stent placement

Preparation Required:

• Standard MRI preparation, including removal of metallic objects and screening for MRI-safe implants
• A kidney function test (eGFR/creatinine) is recommended to assess eligibility for contrast dye
• Fasting may be advised for 4–6 hours before the scan, particularly if intravenous contrast will be used
• Inform the radiology team of any history of allergic reactions, implanted devices, or claustrophobia

How is the procedure performed?
The patient lies still in the MRI scanner while a series of images are taken. Gadolinium-based contrast is injected intravenously to enhance the visualization of the aorta and its branches. The scan takes approximately 45 to 60 minutes and is performed in a quiet, controlled setting with continuous monitoring. Advanced imaging techniques allow for three-dimensional reconstructions of the entire aortic anatomy.
Risks & Safety:
MRI of the whole aorta is non-invasive and radiation-free. The gadolinium contrast agent used is generally well tolerated, though allergic reactions are rare. The test is contraindicated in patients with severe renal impairment unless a non-contrast study is specifically tailored. Always inform your provider about any implants, metal fragments, or pregnancy before the procedure.
Results:
A radiologist experienced in vascular imaging will review the study and generate a detailed report that includes measurements of aortic diameter, identification of any dilations, tears, plaques, or vessel wall abnormalities, and an assessment of blood flow dynamics. These findings help guide further management, which may include medical treatment, surgical planning, or ongoing monitoring.
Short Statement:
An advanced scan that captures the entire aorta — from chest to abdomen — to detect aneurysms, dissections, or structural anomalies without exposure to radiation.
