We investigated the feasibility of imaging the upper arm using real-time and cine MRI during air cuff inflations in order to characterize the elastic properties of the brachial artery. Both the cine, as well as the real-time MR image data allow the direct observation of the occlusion and re-opening of veins and arteries as a function of cuff pressure. They could therefore be potentialy well suited to estimate the elastic properties of the brachial artery, e.g. the area-pressure curve, in vivo. Furthermore, the MR data allow observing the compression and displacement of arm tissue with the future aim to validate and extend existing models of the auscultatory and oscillometric blood pressure measurements.
