Vascular Laboratories at Parnassus

The UCSF Vascular Laboratories are a joint program of Vascular Surgery and Neurology that uses noninvasive procedures to confirm vascular conditions or identify the severity of a vascular disorder. Patients are examined using advanced ultrasound and other technologies, such as pulse volume recorders, that evaluate blood flow without injections and without pain. The lab also measures the success of treatments for vascular conditions.

The lab has two locations:

What to Expect

    All studies performed in the laboratory are noninvasive, meaning they don't require any incisions or needles. In fact, many patients are so relaxed that they fall asleep during the test.

    Ultrasound typically requires applying gel to the skin and applying a transducer — a device that converts energy into ultrasound — on the gel-covered areas to create images of blood vessels. Depending on the study, your test may take up to one hour.
