310 Cross correlation on 2D PCMR velocity data to determine aortic pulse wave velocity

Year: 2008

Type: article

Abstract: Aortic stiffness, as measured by pulse wave velocity (PWV), is an index of cardiovascular health and has predicted mortality in several patient groups. Aortic PWV may be estimated by dividing the distance between two transverse PCMR slice locations by the time differential of flow wave arrival times (transit time method). The arrival times of the flow wave are usually determined by estimating the temporal position of the foot of the flow waveform. Alternately, a PCMR slice can be acquired in the aortic plane and the flow wave measured at many locations in the descending aorta (multi-site method). A regression line may then be fit to the data to estimate central aortic PWV.
