The term vascular refers to the blood vessels. Therefore, vascular ultrasound imaging refers to the examination of the body’s circulatory system. This scan studies the speed and volume of blood flow using the Doppler phenomenon. This scan also examines arteries for atherosclerotic disease.
Areas to be examined are as follows:
- DVT Deep Vein Thrombosis ( blood clot ) in arms or legs
- Arteries for flow limiting stenosis (usually leg arteries)
- Peripheral veins to assess varicosities and venous reflux (insufficiency)
Medical ultrasound scans are currently the most widely used imaging technique in the diagnosis of vascular disease. It can sometimes be used as a standalone examination. Indications like pain on walking or swelling of limb suspicion of vascular insufficiency. The patient is lying down on an examination table or it is sometimes necessary to have them examined while standing to assess the competency of the lower leg veins.
