Variable-density one-shot Fourier velocity encoding.
In areas of highly pulsatile and turbulent flow, real-time imaging with high temporal, spatial, and velocity resolution is essential. The use of 1D Fourier velocity encoding (FVE) was previously demonstrated for velocity measurement in real time, with fewer effects resulting from off-resonance. The application of variable-density sampling is proposed to improve velocity measurement without a si...
متن کاملIn vivo assessment of carotid wall shear rate using spiral Fourier velocity encoding
Introduction: Arterial wall shear stress is widely believed to influence the formation and growth of atherosclerotic plaque [1-3], however, there is currently no gold standard for its in vivo measurement. High-resolution phase contrast is impractical due to partial-volume effects, long scan times, and inadequate SNR. In 1995, Frayne and Rutt [4] proposed a novel method for non-invasively estima...
متن کاملImaging High-Speed Jets Using Rapid Ungated Fourier Velocity Encoding
Introduction: Accurate quantitation of the peak arterial jet velocity is crucial in assessing the severity of cardiovascular disease. The current “gold standard”, Doppler ultrasound, is highly sensitive to beam position and Doppler angle. Fourier velocity encoding (FVE) resolves the full velocity spectrum [1], but conventional gated methods [2-4] do not work well during arrhythmia and require l...
متن کاملHigh resolution slice-selective Fourier Velocity Encoding using spiral SENSE with velocity unwrap
Background In patients with congenital heart disease (CHD), it is desirable to accurately measure peak velocity (Vmax). Unfortunately, phase-contrast MR (PCMR) tends to underestimate peak velocities. Fourier Velocity Encoding (FVE) can measure peak velocities in MRI, but is not commonly used due to long acquisition times. Therefore, we have developed a FVE sequence that combines spiral trajecto...
متن کاملVelocity unwrap for high resolution slice-selective Fourier Velocity Encoding using spiral SENSE
Background In patients with stenoses, it is desirable to accurately measure peak velocity (Vmax). Unfortunately, phasecontrast MR (PCMR) tends to underestimate peak velocities. Fourier Velocity Encoding (FVE) can measure peak velocities in MRI, but is not commonly used due to long acquisition times. We have developed a FVE sequence that combines spiral trajectories with parallel imaging (SENSE)...
