Non-Invasive Blood Flow Studies
Vascular Ultrasound. Painless techniques using ultrasound to record size, motion, blood flow, and composition of the heart, veins, and arteries. Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Vascular ultrasound provides pictures of the body's veins and arteries.
Doppler Ultrasound. A Doppler ultrasound study may be part of a vascular ultrasound examination. Doppler ultrasound is a special ultrasound technique that evaluates blood as it flows through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck. This procedure can locate blockages (stenosis) and abnormalities like blood clots or plaque so that the interventional radiologists can plan for effective treatment.
MRA (Magnetic Resonance Angiography) and CTA (Computed Tomographic Angiography)
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. An angiogram uses imaging methods and, in some cases, a contrast material, to produce pictures of major blood vessels throughout the body. Physicians use this procedure to identify disease and/or aneurysms in the aorta or in other major blood vessels, as well as to detect atherosclerosis disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke, among other diagnoses.
Magnetic Resonance Angiography (MRA). A powerful magnetic field, radio waves and a computer produce the detailed images. MR angiography does not use x-rays, and may be performed with or without contrast material.
Computed Tomographic Angiography (CTA). An alternative to MRA procedures for individuals with a pacemaker, port, or other metal fragments somewhere in the body. CT Angiography shows clarity of blood vessels, differentiation between arteries and veins and, unlike MRA imaging, CT Angiography can capture evidence of calcium deposits.
