The St. Louis Vascular Center offers you additional convenience and thorough care by having a registered ultrasound technician on staff. With state-of-the art ultrasound equipment, we have the ability to perform noninvasive vascular tests in our office, such as Doppler ultrasounds, which are done to measure and assess the flow of blood through arteries and veins. This gives you the convenience of immediate results and combined interaction with your physician and the technologist.
