Physicians at the Presbyterian Cardiovascular Institute Aortic Center use a range of diagnostic tests to determine the appropriate course of treatment for aortic disease.
The size and location of an aortic aneurysm is very important when determining the appropriate course of treatment. Sometimes, multiple imaging studies are needed to analyze the aortic condition before moving forward with treatment.
Types of Imaging Tests
Contrast Angiography
This is an invasive procedure that is only used in a small percentage of cases. Typically, patients who require contrast angiography have a complicated aortic anatomy, and the test is performed as part of the preoperative evaluation.
CT Scan
CT scans (computed tomography) yield high-quality images of the aorta. This is an excellent approach for patients with a complicated aortic anatomy, because it creates a three-dimensional image of the entire aorta that can be studied from multiple angles. This allows physicians to pinpoint the problem in the aorta and appropriately plan for surgery. Learn More
MRA
MRA (magnetic resonance angiography) is an advanced MRI that uses a dye (contrast) called gadolinium, which is safer for the kidneys. MRA is an option when the branch vessels of the aorta need to be studied. MRA can also create three-dimensional pictures of the aorta.
MRI
MRI (magnetic resonance imaging) creates images of the aorta from multiple angles. MRI is often used instead of CT scans for patients who suffer from kidney failure or are allergic to the IV dye (contast material) that is required for CT scans. Learn More
Ultrasound
Ultrasound is the most common evaluation tool. This noninvasive procedure uses sound waves to determine the size and location of an aneurysm in the abdomen. If you have a small aneurysm (less than four centimeters, or the size of an egg), an ultrasound is usually performed annually until surgery is needed. Ultrasound is also used for long-term follow-up after surgery. Learn More
