Quantification 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...
متن کاملQuantification of aortic stiffness using MR elastography and its comparison to MRI-based pulse wave velocity.
PURPOSE To determine the correlation in abdominal aortic stiffness obtained using magnetic resonance elastography (MRE) (μ(MRE)) and MRI-based pulse wave velocity (PWV) shear stiffness (μ(PWV)) estimates in normal volunteers of varying age, and also to determine the correlation between μ(MRE) and μ(PWV). MATERIALS AND METHODS In vivo aortic MRE and MRI were performed on 21 healthy volunteers ...
متن کاملCorrelates of Aortic Pulse wave velocity measured by cardiac MRI
Methods 223 consenting nondiabetic, normotensive volunteers without clinical cardiovascular disease or echocardiographic abnormalities (124 females, 116 hyperlipidemic (42 treated), age: 58.6+/-14.9yrs, BMI: 24.8+/-3.3 (24 with BMI>28) were studied. CMR studies were performed on a 1.5 Tesla MR scanner (Siemens, Germany) using a phased array surface-coil and a spine-coil array. PWV was assessed ...
متن کاملCentral aortic pressure influences pulse wave velocity.
Central Aortic Pressure Influences Pulse Wave Velocity To the Editor: The study reported by Lantelme and colleagues1 suggests that increasing heart rate is independently associated with higher aortic pulse wave velocity (PWV). We are concerned that the authors of this study have neither addressed the impact of central aortic pressure changes on PWV nor the presence of potential bias in their st...
متن کاملPulmonary pulse wave velocity as assessed with velocity-encoded MRI
Methods In 15 healthy volunteers (7 male; mean±SD age 19±6 years) pulmonary PWV was prospectively assessed between the proximal main pulmonary artery (MPA) and just before the first branching of the distal left pulmonary artery (LPA). One-directional through-plane velocity-encoded (VE) MRI using breath holds was used to assess the pulmonary flow at the levels of MPA and distal LPA with a tempor...
