The test is done in the ultrasound or radiology department, a hospital room, or in a peripheral vascular lab.
During the exam:
- A water-soluble gel is placed on a handheld device called a transducer. This device directs high-frequency sound waves to the artery or veins being tested.
- Blood pressure cuffs may be put around different parts of the body, including the thigh, calf, ankle, and different points along the arm.
