What Is a Doppler Exam?
A Doppler exam is a non-invasive test that uses high-frequency sound waves to assess blood flow in blood vessels. It helps identify blockages or abnormalities that can affect circulation. The test is commonly used to evaluate blood flow in arteries and veins in areas such as the neck, legs, or arms. It is helpful in diagnosing conditions like peripheral artery disease, deep vein thrombosis, and carotid artery disease. By analyzing blood flow patterns, Doppler exams assist in detecting potential risks for heart attacks, strokes, or other vascular issues.
During the exam, a gel is applied to the skin, and a handheld device called a transducer is moved over the area being examined. The transducer emits sound waves and measures the echoes that bounce back from moving blood cells. This data is then translated into a visual representation or sound, allowing healthcare providers to evaluate the blood flow. Doppler exams are quick, painless, and provide valuable insights into vascular health, making them essential for diagnosing circulatory problems.
