Doppler vs duplex ultrasound
Patients often say Doppler ultrasound when they mean vascular duplex. Duplex combines vessel imaging with Doppler flow assessment, giving information about structure, direction of flow, and flow speed.
Common reasons for Doppler testing
Doppler testing may be requested for suspected DVT, varicose vein mapping, leg artery narrowing, diabetic foot circulation, carotid artery narrowing, and vascular access planning.
