A Vascular Doppler is a medical diagnostic tool used to review the body’s circulatory system to identify irregularities and concerns with blood flow in large arteries and veins. A Vascular Doppler units perform a range of very valuable vascular assessments to help diagnose vascular diseases and life threatening conditions. Vascular assessments are critical to evaluate the health of the vascular system and to help prevent serious cardiac events.
Vascular Doppler units range from basic units that perform high level vascular assessments to more advanced models that additionally perform diabetic foot assessments, ankle brachial pressure index tests (ABPI), peripheral arterial disease tests (PAD), toe-brachial index tests (TBI), segmental vascular assessments, stress tests, and more. These tests help identify vascular conditions that can cause heart attacks, strokes, and even death.
Vascular Doppler units are available in a range of sizes from portable handheld unit to larger cart/table models. Vascular Doppler units can be manual, semi-auto, or automatic. Some models have a speaker to listen for the results while some have colorful displays and they can be integrated with computers.
Vascular Doppler tests are non-invasive and painless. The vascular unit uses sound waves to produce images of the body’s veins and arteries for diagnosis. During a Doppler ultrasound, the physician or sonographer uses a small hand-held transducer (probe) to produce the sound waves on the desired areas. Depending on the results of the vascular ultrasound, the physician may order a more invasive procedure (arteriography and venography) to inject dye into the vessels for x-ray evaluation.
