Registered Vascular Technologists Profiles

Detailed vascular (venous color duplex) ultrasound examinations are essential to properly diagnose, treat, and follow patients with venous problems.

Our Registered Vascular Technologists (RVTs) are very experienced and skilled at performing venous color duplex ultrasound studies of veins of the extremities and of the abdomen and pelvis. The attention to anatomical details and the careful evaluation of venous flow makes the VCOTN vascular laboratory unique in our area. The quality of vein treatment is only as good as the underlying diagnostic ultrasound studies available to the treating physician.
