Ultrasound Angiography is a non-invasive imaging technique used to visualize blood vessels and assess blood flow. It employs high-frequency sound waves to create real-time images of the vascular system, helping to identify conditions like blockages or abnormalities in arteries and veins. This method is safe and does not involve radiation, making it suitable for various patients, including those with allergies to contrast agents. Ultrasound can be used in different areas of the body, such as the heart, legs, and neck, providing valuable information for diagnosing cardiovascular diseases.
