Vascular ultrasound, also known as vascular Doppler ultrasound, usually costs around $150. Vascular Doppler ultrasonography mainly uses a Doppler ultrasound probe to observe the direction and speed of blood flow in the blood vessels, which can clarify whether there are stenosis, thrombus, occlusion-like changes, plaques, etc., as well as aneurysms, vascular malformations, arteriovenous fistulae, and entrapments in the blood vessels. Ultrasound examination of blood vessels is a non-invasive examination method. It is relatively simple to operate at the bedside and is generally the most commonly used method of vascular examination. Therefore, vascular ultrasonography is generally cheaper. The above costs are for reference only, different regions and hospitals are graded differently, as well as different inspection equipment, will also have an impact on the cost of the examination.
