Fast semi-automated analysis of pulse wave velocity in the thoracic aorta using high temporal resolution 4D flow MRI
Background Pulse wave velocity (PWV) gives an indication of vessel stiffness, which can be used as a marker of age related changes in compliance, as well as to assess changes in vessel elasticity as a measure of atherosclerosis [1,2]. A recent meta-analysis showed PWV to be a robust predictor for cardiovascular events and all-cause mortality [3]. Recently, 4D flow MRI has been applied to assess...
متن کاملPulse wave velocity with 4D flow MRI: systematic differences and age-related regional vascular stiffness.
PURPOSE The objective of this study was to compare multiple methods for estimation of PWV from 4D flow MRI velocity data and to investigate if 4D flow MRI-based PWV estimation with piecewise linear regression modeling of travel-distance vs. travel time is sufficient to discern age-related regional differences in PWV. METHODS 4D flow MRI velocity data were acquired in 8 young and 8 older (age:...
متن کاملGlobal Pulse Wave Velocity in 87 Patients with Acute Ischemic Stroke and Aortic Atherosclerosis
Introduction: Increased pulse wave velocity (PWV) as a measure of aortic stiffness is an important marker for changes in aortic compliance and is an independent predictor of cardiovascular mortality and stroke. Reliable measurement of PWV is of particular interest for monitoring the progression or regression of vessel compliance during therapy [1-3]. Phase contrast (PC) MRI provides a noninvasi...
متن کاملQuantification of aortic pulse wave velocity in preterm infants using 4D phase contrast MRI
Background 4D phase contrast (PC) MRI sequences providing full coverage of the aortic arch were acquired in neonates. Aortic pulse wave velocity (PWV) was then calculated from flow measurements taken at 5 to 8 locations along the arch and the aortic length between each location. Neonatal PWV values were compared with previously published adult values. Mechanical compliance within the healthy an...
