Non-Invasive Vascular USAn ultrasound image is a useful way of evaluating the body's circulatory system. Ultrasound images are captured in real-time, so they can help radiologists monitor the blood flow to organs and within arteries and veins throughout the body. Ultrasound imaging of the body's veins and arteries can help the radiologist see and evaluate blockages to blood flow, such as clots in veins and plaque in arteries. With knowledge about the arterial blood flow gained from an ultrasound image, the radiologist can often determine whether a patient is a good candidate for a procedure like angioplasty.
Ultrasound images may also be used to plan or review the success of procedures that graft or bypass blood vessels. Ultrasound of the veins may reveal blood clots that require treatment, such as anticoagulant therapy (blood thinner), or filters to prevent clots from traveling to the lungs (embolism). Ultrasound of the vascular system also provides a fast, noninvasive means of identifying blockages of blood flow in the neck arteries to the brain that might produce a stroke or mini-stroke.
