چکیده

Background The effects of off-resonance frequency errors during spiral readouts [Yudilevich and Stark, 1987] are known. Here we explain previously unrecognised intra-voxel dephasing consequences of two sources of phase curvature over the vessel cross-section in through-plane flow imaging using spirals i.e. off-resonance and the velocityencoded phase-shift, including the consequences for invivo measurements.

Rapid quantitation of high-speed flow jets.

Flow jets containing velocities up to 5-7 m/s are common in patients with congenital defects and patients with valvular disease (stenosis and regurgitation). The quantitation of peak velocity and flow volume in these jets is clinically significant but requires specialized imaging sequences. Conventional 2DFT phase contrast sequences require lengthy acquisitions on the order of several minutes. ...

Heat transfer enhancement in a spiral plate heat exchanger model using continuous rods

This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger in the cross-stream plane. The vortex generators are located at various azimuth angles of α=30◦, 60◦, 90◦, and 120◦ with non-dimensional diame...

Effect of Phase-Encoding Reduction on Geometric Distortion and BOLD Signal Changes in fMRI

Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...

Measurement of Fast Flow Jets using Short-TR Spiral Phase Contrast

The quantification of valvular regurgitations requires the accurate measurement of fast flow jets of 5-7 m/s. Conventional phase contrast imaging sequences are usually corrupted by flow artifacts at these high velocities. We present a CINE gated breath held method based on short-TR spiral phase contrast, which has a sufficiently short measurement time (< 4 ms) to minimize flow artifacts. Simula...

Real-Time Color overlay Cardiac Phase Contrast Spiral imaging at 3 Tesla

Introduction: The ability of MRI to quantify blood flow with high spatial and temporal resolution has made it a method of choice for accurate blood flow mapping in-vivo. The challenges comprise the development of techniques to accurately assess blood flow through heart valves by incorporating appropriate respiratory and cardiac motion compensation schemes as well as very fast measurement techni...
