Abstract

Quantitative 2D digital subtraction angiography (qDSA) is a postprocessing technique that leverages the inherent pulsatility in arterial blood to quantify blood velocity1. It has been correlated with intravascular Doppler and 4D Flow MRI in normal porcine iliac arteries and was used to quantify velocities in a stenotic iliac artery phantom model2-3. This study aimed to assess the feasibility of using qDSA to quantify blood velocity in an in vivo porcine stenotic iliac artery model.
