It combines a standard ultrasound picture of anatomy with Doppler measurements of moving blood. It is commonly used to evaluate arteries and veins in the neck, arms, legs, abdomen, and around surgical grafts or dialysis access. Clinicians use it to help explain symptoms, estimate disease severity, and guide next-step testing or treatment planning."}
