  1. Test Re-Test Reliability of Brachial Artery Flow-Mediated Dilation in Healthy Adults

    Richardson, TaraWake Forest University2016

    Ultrasonographic assessment of flow mediated dilation (FMD) is a valuable noninvasive measurement of endothelial function; it has been shown to be a useful prognostic tool for cardiovascular disease risk. However, reproducibility of FMD in the literature varies greatly (Coefficient of Variations …
