Since its inception, scientists have refined their ... (Doppler … Flow-mediated dilation (FMD) refers to dilation (widening) of an artery when blood flow increases in that artery. The primary cause of FMD is release of nitric oxide by endothelial cells. To determine FMD, brachial artery dilation following a transient period of forearm ischemia is measured using ultrasound. Because the value of FMD can be compromised when improperly applied, attempts have been made to standardize the methodology for measuring FMD.
