How is CVI diagnosed?

To diagnose CVI, your doctor will perform a complete medical history and physical exam. During the physical exam, the doctor will carefully examine your legs.A test called a vascular or duplex ultrasound may be used to examine the blood circulation in your legs. During the vascular ultrasound, a transducer (small hand-held device) is placed on the skin over the vein to be examined. The transducer emits sound waves that bounce off the vein. These sound waves are recorded, and an image of the vessel is created and displayed on a monitor.
