Doppler Ultrasound Tests           A Doppler Ultrasound test uses reflected sound waves to evaluate blood as it flows through a blood vessel. It helps doctors evaluate blood flow through the major arteries and veins of the arms, legs, and neck. It can show blocked or reduced blood flow through narrowing in the major arteries of the neck that could cause a stroke. Therefore, this test is extremely effective in not only evaluation but prevention as well.     Doppler Ultrasound tests are conducted by a qualified technician and digitally transferred for future reference. Cost for Doppler Ultrasound testing is $60
