A dual-slice k-t approach for highly accelerated flow MRI
نویسندگان
چکیده
Background Phase contrast MRI has limited practical value in clinical applications due to its inherently long scan times [Kilner,JCMR’07]. Parallel imaging[Pruessmann, MRM’01] and spatio-temporal constrained reconstruction techniques[Tsao,MRM’03] have been shown beneficial[Baltes,MRM’05]. Dual slice approaches have shown advantages as compared to standard SENSE when multiple and sufficiently separated slices are acquired[Breuer, MRM’10]. We present a combination of dual slice excitation with undersampled flow imaging by modifying the k-t SENSE reconstruction framework to include sensitivity information in through-slice direction.

Improving cardiac cine MRI on 3T using 2D k-t accelerated auto-calibrating parallel imaging
Background Recently, 3D cine has gained attention due to its capability for single breath-hold volumetric measurement [1]. Nonetheless, conventional 2D cine maintains two intrinsic advantages, namely, its superior blood-myocardium contrast owing to blood in-flow effects and reduced SSFP banding artifacts with more localized slice-by-slice shimming. These advantages are more prominent at high fi...

Background Hemodynamic parameters are known to play a crucial role in the growth and rupture of intracranial aneurysms [Appanaboyina IntJNumerMethodsFluids2008]. Flow diverting stents have emerged as an alternative to coiling by using fine meshes to divert flow away from the aneurysm sac to promote thrombus formation and remodeling of the aneurysm while keeping side branches and perforating art...

INTRODUCTION: First-pass cardiac perfusion MRI requires fast data acquisition to achieve an appropriate combination of temporal resolution, spatial resolution and spatial coverage for clinical studies [1]. We have recently presented a combination of compressed sensing and parallel imaging (k-t SPARSE-SENSE) to highly accelerate perfusion studies by jointly exploiting sparsity in the combined sp...

BACKGROUND Whole-heart first-pass perfusion cardiovascular magnetic resonance (CMR) relies on highly accelerated image acquisition. The influence of undersampling on myocardial blood flow (MBF) quantification has not been systematically investigated yet. In the present work, the effect of spatiotemporal scan acceleration on image reconstruction accuracy and MBF error was studied using a numeric...

INTRODUCTION: First-pass cardiac perfusion MRI is a promising modality for the assessment of coronary artery disease. Recently developed dynamic parallel imaging techniques, such as k-t SENSE [1] and k-t GRAPPA [2], can be used to perform up to 10-fold accelerated perfusion imaging by exploiting the difference in coil sensitivities and spatio-temporal correlations. Such techniques can be used t...
