Elizabeth is a Registered Vascular Technologist in the Department of Vascular Surgery, Stanford Health Care, USA.
Why I love to teach
I am a cardiac and vascular sonographer in Palo Alto, California. My 13-year sonography experience in trauma and surgical settings led me to Stanford University’s hospital. I love learning from our rotating students, interns, residents, and fellows, while teaching them the basics of vascular ultrasound.

Dialysis is a lifesaving treatment, but a specialized vascular access is required to undergo the procedure. Learn more about the clinical decision-making process leading to arteriovenous (AV) fistula placement.
Venous ultrasound course: identifying varicose veins in the insufficiency study
Ultrasound learners find it tricky to tell varicose veins from the great saphenous vein (GSV) and the small saphenous vein (SSV). In this video, you'll learn how identify varicose veins with confidence and what to do if you find a blood clot in a varicose vein.
Venous ultrasound course: deciphering DVT waveforms
A pulsed wave (PW) Doppler study is an integral part of venous ultrasound. This video explains how to interpret the waveform graph to find out whether a vein contains a clot, where the clot is located and if the patient suffers from venous insufficiency.
Venous ultrasound class: executing a DVT ultrasound study
Students benefit from a clear step-wise approach to screening for a deep vein thrombosis (DVT). In this video, Elizabeth Tenny, from the Stanford Vascular Lab, focuses on femoral vein imaging and explains where to start the study, what techniques to use, and how to approach anatomical variations.
Venous ultrasound course: interpreting DVT compressibility and chronicity on ultrasound
Deep vein thrombosis (DVT) is a common clinical problem, affecting around 500 000 Americans yearly, according to the CDC. Diagnosing a DVT can be simple, if we master the most important technique of DVT ultrasound–checking for compressibility. In this video, our expert Elizabeth Tenny, from the Stanford Vascular Lab, explains how to diagnose a dangerous clot and what a venous ultrasound beginner can mistake for a DVT.
Performing a manual ankle-brachial index (ABI)
In this video, Dr Elizabeth Tenny will take you through this procedure, step-by-step, pointing out the common pitfalls and how to avoid them.
Evaluating stents and bypass grafts
Knowing how to evaluate and recognize a stent or bypass graft in patients who've had them is a critical skill all clinicians should have. In this video, we'll show you how to identify and assess them, and differentiate between the artery and the graft.
