duplex scanning

Duplex scanning is a medical diagnostic technique that combines two types of ultrasound imaging: B-scan and Doppler imaging. The B-scan provides a two-dimensional image of internal organs, while the Doppler imaging measures blood flow. By integrating these two methods, duplex scanning can identify arteries and simultaneously assess their blood flow. This technique is particularly useful for diagnosing conditions like heart valve defects and arterial diseases. Ultrasound, in general, uses high-frequency sound waves to create images of internal body structures and is a non-ionizing form of energy, making it a safer alternative to X-rays in many diagnostic situations.1
