Flexible phase-encoding in 3D coronary MRA with balanced SSFP

چکیده
Fig. 3. Comparison of PE schemes in bSSFP CMRA of the right coronary artery. Conspicuity of the distal RCA was good in all three schemes. Fig. 2. Flexible PE schemes with partial Fourier acquisition in the PE (kY) dimension and k-space corners removed from sampling, colorized from red to blue to reflect the sequence of acquisition. Plots of the first and last acquisition trains are shown, reflecting centric ordering in the SE (kZ) dimension. Flexlinear (a) has large ‘steps’ in k-space, whereas compact-flex-linear (b) has smaller steps due to grouping of the sampling matrix in the PE dimension that limit large steps when sorting in the SE dimension.

OBJECTIVE To validate the optimal cardiac phase and appropriate acquisition window for three-dimensional (3D) whole-heart coronary magnetic resonance angiography (MRA) with a steady-state free precession (SSFP) sequence, and to compare image quality between SSFP and Gd-enhanced fast low-angle shot (FLASH) MR techniques at 1.5 Tesla (T).

Purpose: While contrast-enhanced MR Angiography (CEMRA) is widely used for evaluation of vascular pathology, recent nephrogenic systemic fibrosis (NSF) concerns following administration of Gadolinium based contrast agents have spurred interest in non-contrast MRA methods. Balanced steady state free precession (bSSFP) imaging [1-3] has shown great promise due to its high SNR and short scan times...
متن کاملComparison of systolic and diastolic 3D SSFP for arterial dimensions and coronary artery origins in patients with congenital heart disease
Background 3D steady-state free precession (SSFP) sequences allow for acquisition of isotropic datasets without the need for IV placement and contrast administration. Similar to MR angiography, they can be post-processed using multiplanar reconstruction, allowing for cross-sectional vessel measurements. They are also ECG-gated, allowing for visualization of coronary artery origins, which cannot...
متن کاملFeasibility of Whole-Heart Coronary MRA on 3 Tesla Using Ultrashort-TR SSFP VIPR
Introduction: Coronary magnetic resonance angiography (MRA) has been performed on 3.0T to generate higher SNR compared to 1.5T. In addition, high blood-to-myocardium contrast could be achieved using the SSFP technique [1]. However, SSFP is highly sensitive to field inhomogeneities. In particular, signal nulls occur every 1/TR in resonance frequency, producing “banding” artifacts in images. With...

Introduction: A non-gadolinium-enhanced MRA technique using ECG-triggered 3D balanced SSFP with flow-sensitive dephasing (FSD) preparation has recently been developed and validated in the distal lower extremities of healthy volunteers [1]. The FSD’s first-order gradient moment, m1, is shown to be the most important parameter to determine angiographic quality. A suboptimal m1 may result in venou...
