Arterial resistivity index
ID: arterial-resistivity-index
The Arterial Resistivity Index (ARI) is a Doppler ultrasound-derived measurement used in vascular studies to assess the resistance of blood flow within arteries. It is often calculated from the peak systolic velocity (PSV) and end-diastolic velocity (EDV) of blood flow in a specific artery.
