P.47 Feasibility Evaluation of Imaging-Free Ultrasound Technology to Measure Diameters of Brachial and Radial Arteries for Assessment of Endothelial Function

Abstract

Background: Ultrasonographic imaging to record changes in peripheral arterial diameter associated with Flow mediated dilatation or Low flow mediated constriction is routinely used to assess various facets of vascular endothelial function. Imaging poses many challenges including requirement of costly ultrasound machines, trained manpower to perform imaging and effortintensive steps to analyse the images subsequently using manual or automated methods. We tested the feasibility and validity of using an imaging-free technology to record resting arterial diameters of brachial and radial arteries.
