Noninvasive Vascular Imaging
The Noninvasive Vascular Imaging Program provides comprehensive imaging and diagnostic services for disorders of the vascular system. The imaging center is accredited by the International Accreditation Commission (formerly the Intersocietal Commission for the Accreditation of Vascular Laboratories), which ensures high-quality care for our patients.
Our Comprehensive Noninvasive Vascular Imaging Laboratory uses state-of-the-art CT scanners, MRI scanners, and ultrasound imaging equipment to diagnose vascular diseases and assist our cardiologists, cardiothoracic surgeons, and vascular surgeons with diagnosing and planning surgical procedures. These imaging studies provide important information required to plan procedures such as aortic aneurysm repair and transcatheter aortic valve repair, a new method of replacing the aortic valve without requiring open heart surgery.
We use a variety of medical examinations to accurately diagnose patients’ vascular conditions. These examinations include:
- Computed Tomography Angiography (CTA)
- A noninvasive exam that uses Computed Tomography (CT) technology to look at the blood vessels. It is used to evaluate abnormal narrowing or enlargement of blood vessels in the chest, abdomen, pelvis, and extremities. Our CTA techniques minimize radiation exposure while providing high-quality diagnostic images. CT angiograms are interpreted by interventional radiologists who, in addition to the training that all radiologists receive, have additional fellowship training in vascular interventional radiology.
- Magnetic Resonance Angiography (MRA)
- A noninvasive exam that uses Magnetic Resonance (MR) technology – not ioning radiation – to look at flow through the blood vessels. MR angiograms are interpreted by diagnostic radiologists who are fellowship trained in MR imaging.
- Vascular Ultrasound
- A noninvasive exam that uses high-frequency sound waves to create images to detect the rate of blood flow through blood vessels. Ultrasound imaging can be used to detect blood clots and narrowed blood vessels throughout the body. It can be used to evaluate varicose veins and determine candidates for endovenous (vein) ablation. Vascular ultrasound images are interpreted by interventional radiologists who, in addition to the training that all radiologist receive, have additional fellowship training in vascular interventional radiology.
