Fast 3D SSFP Imaging Using a Concentric Cylinders Trajectory
Introduction: A 2D concentric rings trajectory is inherently centric-ordered, provides a smooth weighting in k-space, and enables shorter scan times [1]. Due to these properties, it is well-suited for magnetizationprepared imaging. Extensions of this trajectory for 3D imaging include: 3D stack-of-rings [2] and 3D interleaved concentric cylinders [3,4]. 3D stack-of-rings trajectory directly inhe...
متن کامل3D magnetization-prepared imaging using a stack-of-rings trajectory.
Efficient acquisition strategies for magnetization-prepared imaging based on the three-dimensional (3D) stack-of-rings k-space trajectory are presented in this work. The 3D stack-of-rings can be acquired with centric ordering in all three dimensions for greater efficiency in capturing the desired contrast. In addition, the 3D stack-of-rings naturally supports spherical coverage in k-space for s...
متن کامل3D Magnetization-Prepared Imaging and Fat/Water Separation Using a Stack-of-Rings Trajectory
Introduction: Acquiring a 3D volume in a short scan time is a high-priority goal of many MR imaging applications. This is especially true for time-sensitive studies, such as magnetization-prepared imaging and dynamic imaging, where the signal is in transition. Fast imaging trajectories, such as under-sampled 3DPR or 3D stack-ofspirals, can provide a great reduction in scan time. However, they a...
متن کاملMR Spectroscopic Imaging Using a Concentric Rings Trajectory
Introduction: MR spectroscopic imaging (MRSI) provides invaluable information regarding in vivo metabolic processes to aid in clinical diagnosis. However, long scan times are required to resolve both the spatial and spectral dimensions. Fast imaging trajectories, such as EPI [1] and spiral [2], can encode multiple dimensions at once, providing a reduction in scan time compared to conventional M...
متن کاملNon-contrast-enhanced Flow-independent Peripheral Angiography using a 3D Concentric Cylinders Trajectory
Introduction: Non-contrast-enhanced flow-independent angiography (FIA) exploits intrinsic tissue parameters such as T1, T2 and chemical shift to generate vessel contrast [1]. Unlike flow-dependent methods, FIA can generate stable vessel contrast even with slow flow potentially in the diseased leg. Magnetization-prepared 3D SSFP sequences have been of interest for FIA [2,3], but an important iss...
