SOMS: Simultaneous Orthogonal Multi- Slice Imaging
Simultaneous multi -s l ice (SMS) MRI has become a popular technique in both research and cl inical practice, as i t provides information about multiple sl ices at the time of a conventional s ingle-sl ice measurement. For technical reasons, SMS is commonly l imited to the acquisi tion of paral lel s l ices. Here, we propose a new Cartesian sequence for the simultaneous excitation of orthogonal...
متن کاملRadial simultaneous multi slice imaging for rapid cardiac imaging
Background It may be possible to more rapidly acquire cine, cardiac perfusion, and Late Gadolinium Enhancement (LGE) images for “free” with Simultaneous Multi-Slice (SMS) methods. With SMS imaging, multiple slices are simultaneously excited and acquired. Here we explore the application of an undersampled radial SMS approach termed Controlled Aliasing In Parallel Imaging results in higher accele...
متن کاملSimultaneous wall and blood-flow phase-contrast imaging using a single low VENC
Background Intra-ventricular blood flow and regional myocardial motion are two key components used in assessing cardiac function. Both can be quantified using phase contrast MRI, but typically require two imaging sequences to be acquired one with a high velocity encoding value (VENC) and one with a low VENC, selected to optimize velocity sensitivity while avoiding aliasing. In an effort to obta...
متن کاملImproving diffusion MRI using simultaneous multi-slice echo planar imaging
In diffusion MRI, simultaneous multi-slice single-shot EPI acquisitions have the potential to increase the number of diffusion directions obtained per unit time, allowing more diffusion encoding in high angular resolution diffusion imaging (HARDI) acquisitions. Nonetheless, unaliasing simultaneously acquired, closely spaced slices with parallel imaging methods can be difficult, leading to high ...
متن کاملCAIPIRINHA accelerated simultaneous multi-slice TrueFISP real-time imaging
Introduction: CAIPIRINHA multi-slice imaging offers the possibility to acquire several imaging slices simultaneously while maintaining the image quality (1), allowing a high acceleration of the imaging procedure. By providing the individual slices with different RF-phase cycles, the simultaneously excited slices are shifted with respect to each other in the FOV, facilitating the separation of t...
