Vascular Laboratory at Parnassus

Vascular ultrasound is a painless, noninvasive procedure that uses sound waves to evaluate how blood moves through your veins and arteries. The UCSF Vascular Laboratory provides the full range of vascular ultrasound exams, including the following:

Abdominal Vascular Exam: Evaluates the blood vessels that bring blood to and away from the abdominal organs
Extracranial Cerebrovascular Arterial Duplex Scan: Evaluates vessels in the head and neck, such as the carotid artery
Transcranial Doppler Study: Studies the blood vessels within the skull that supply the brain
Venous and Arterial Study of Legs and Arms: Evaluates blood flow from the legs and arms to the heart

Vascular ultrasounds may take up to an hour, depending on the study.

We see patients with the following conditions:

Abdominal aortic aneurysms
Carotid artery disease
Cerebrovascular disease and stroke
Chronic vein disease, such as varicose veins
Deep vein thrombosis (blood clots)
Mesenteric artery disease (narrowing of the arteries that supply blood to the intestines)
Peripheral artery disease in arms, hands, legs or feet
Renal (kidney) artery disease
