Arterial Doppler ??? Cardiac Doppler??? @ "diagnosticcentrepune.in" A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs. Vascular flow studies, also known as blood flow studies, can detect abnormal flow within an artery or blood vessel. A Doppler ultrasound may help diagnose many conditions, including: Blood clots Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency) Heart valve defects and congenital heart disease A blocked artery (arterial occlusion) Decreased blood circulation into your legs (peripheral artery disease) Bulging arteries (aneurysms) Narrowing of an artery, such as in your neck (carotid artery stenosis) A Doppler ultrasound can estimate how fast blood flows by measuring the rate of change in its pitch (frequency). During a Doppler ultrasound, a technician trained in ultrasound imaging (sonographer) presses a small hand-held device (transducer), about the size of a bar of soap, against your skin over the area of your body being examined, moving from one area to another as necessary. This test may be done as an alternative to more-invasive procedures, such as angiography, which involves injecting dye into the blood vessels so that they show up clearly on X-ray images. A Doppler ultrasound test may also help your doctor check for injuries to your arteries or to monitor certain treatments to your veins and arteries We have Best sonologist for this kind of studies.
