Early and accurate diagnosis of vascular conditions is essential for preventing complications such as stroke, aneurysms, and poor circulation. CT angiography (CTA) and MR angiography (MRA) are non-invasive imaging techniques that provide detailed 3D views of arteries and veins, allowing vascular specialists to identify blockages, narrowing, and abnormal blood flow with exceptional clarity.
At Vascular Surgery Associates in Los Angeles & Santa Monica, we use CTA and MRA imaging to detect and monitor vascular diseases, ensuring patients receive the most effective treatments for improved circulation and long-term health.
What Are CT Angiography & MR Angiography?
Both CTA and MRA are highly advanced vascular imaging techniques that provide detailed pictures of the arteries and veins without requiring an invasive catheter procedure.
CT Angiography (CTA)
Uses X-ray technology and contrast dye to produce high-resolution, 3D images of blood vessels, helping detect aneurysms, blockages, and arterial disease.
MR Angiography (MRA)
Uses magnetic resonance imaging (MRI) and contrast agents to create detailed images of blood flow without radiation exposure.
These imaging tests help vascular surgeons develop customized treatment plans based on precise diagnostic results.
When Is CT or MR Angiography Recommended?
CTA and MRA are commonly used to diagnose and assess conditions such as:
Peripheral Artery Disease (PAD)
Identifying blockages in the legs and feet
Aneurysms (AAA & TAA)
Detecting weakened or bulging blood vessels
Carotid Artery Disease
Evaluating stroke risk from narrowed arteries in the neck
Deep Vein Thrombosis (DVT) & Blood Clots
Locating and assessing clot severity
Renal Artery Stenosis
Determining blockages affecting kidney function
Thoracic Outlet Syndrome
Evaluating blood vessel compression in the upper body
Mesenteric Ischemia
Assessing reduced blood flow to the intestines
Benefits of CT & MR Angiography for Vascular Diagnosis
Compared to traditional catheter-based angiography, CTA and MRA offer:
- Non-invasive imaging with no need for an arterial catheter
- Highly detailed 3D images of blood vessels for accurate diagnosis
- Rapid results for quick treatment planning
- Minimal discomfort with no lengthy recovery period
- Lower risk of complications compared to invasive procedures
How the Procedure Works
CT Angiography (CTA)
- A contrast dye is injected into a vein to highlight blood vessels.
- A CT scanner captures high-resolution images of circulation in the arteries and veins.
- Advanced software reconstructs a 3D model, allowing specialists to detect narrowing, clots, or aneurysms.
MR Angiography (MRA)
- Patients lie inside an MRI machine, which uses magnetic fields and radio waves to scan blood vessels.
- A contrast agent may be used to enhance blood flow visualization.
- Detailed images are produced, providing vascular specialists with a comprehensive view of circulation.
Who Should Consider CT or MR Angiography?
These imaging tests are ideal for patients who:
- Experience symptoms of vascular disease (leg pain, swelling, numbness, or cramping)
- Have a history of high blood pressure, diabetes, or smoking
- Are at risk for aneurysms, PAD, or carotid artery disease
- Need vascular evaluation before surgery or minimally invasive procedures
- Have had previous vascular interventions and require follow-up imaging
