Quantitative assessment of myocardial motion from velocity encoded MRI
Methods 11 Volunteers (30±8 years) and 3 patients (41±11 years) were investigated at a 3T whole body MR scanner (Achieva, Philips) with a 32 channel cardiac coil. The patients suffered from DCM, asynchrony and/or LBBB. A velocity encoded (TPM) navigated segmented gradient echo sequence was applied in the apical, equatorial and basal slice. The acquisition parameters were: FOV=340mm, in-plane re...
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...
متن کاملHigh-resolution, high-SNR velocity maps reconstructed from low-resolution Fourier velocity encoded MRI data
Introduction: Fourier velocity encoding (FVE) provides considerably higher SNR than phase contrast (PC), due to its higher dimensionality and larger voxel sizes. FVE is also robust to partial voluming, as it measures the velocity distribution of the spins within each voxel. FVE data are typically acquired with low spatial resolution, due to scan-time restrictions associated with its higher dime...
متن کاملComputational fluid dynamics simulations guided by Fourier velocity encoded MRI
Introduction: Fourier velocity encoding (FVE) is a promising MRI method for assessment of cardiovascular blood flow. FVE provides considerably higher signal-to-noise ratio (SNR) than phase contrast (PC) imaging, and is robust to partial-volume effects. On the other hand, FVE does not directly provide velocity maps. These maps are useful for calculating the blood flow through a vessel, or for gu...
متن کاملVolumetric motion quantification by 3D velocity encoded MRI
Methods 12 volunteers (26±7 years) and 2 patients (46, DCM/29, LBBB) were investigated at a 3T whole body MR scanner (Achieva, Philips) with a 32 channel cardiac coil. A 3D black blood velocity encoded navigated segmented gradient echo sequence (3D-TPM) was applied for whole heart coverage. The acquisition parameters were: FOV=380mm, isotropic resolution of 3x3x3mm, FOV in through-plane directi...
