What is the primary purpose of vascular ultrasound?

The primary purpose of vascular ultrasound is to assess blood circulation and diagnose vascular conditions. This non-invasive imaging technique uses high-frequency sound waves to produce images of blood vessels and blood flow. By visualizing the circulatory system, healthcare providers can identify issues such as blockages, thrombosis, aneurysms, and venous reflux. The detailed, real-time images of blood flow help in diagnosing various vascular disorders, guiding treatment decisions, and monitoring the effectiveness of interventions.

Other options focus on different physiological systems; for instance, measuring heart rate and rhythm pertains specifically to cardiac function rather than vascular assessment. Evaluating respiratory function deals with the lungs and breathing, while analyzing cardiac output is directly related to heart performance. These areas, while important in their own right, do not encompass the primary aim of vascular ultrasound.
