Clinical Feasibility of Accelerated, High Spatial Resolution Myocardial Perfusion Imaging

Clinical feasibility of accelerated, high spatial resolution myocardial perfusion imaging.

OBJECTIVES The aim of this study was to assess the clinical feasibility and diagnostic performance of an acceleration technique based on k-space and time (k-t) sensitivity encoding (SENSE) for rapid, high-spatial resolution cardiac magnetic resonance (CMR) myocardial perfusion imaging. BACKGROUND The assessment of myocardial perfusion is of crucial importance in the evaluation of patients wit...

High-Resolution Imaging of Myocardial Perfusion

INTRODUCTION Dynamic imaging of myocardial perfusion imaging after injection of a contrast agent is a major tool for noninvasive assessment of the physiological conditions of heart tissues. To make myocardial perfusion imaging more practically useful, the dynamic contrast-enhanced (DCE) images need to have high spatiotemporal resolution, which cannot be achieved by the conventional imaging meth...

Accelerated High Spatial Resolution Diffusion-Weighted Imaging

Acquisition of a series of anisotropically oversampled acquisitions (so-called anisotropic "snapshots") and reconstruction in the image space has recently been proposed to increase the spatial resolution in diffusion weighted imaging (DWI), providing a theoretical 8x acceleration at equal signal-to-noise ratio (SNR) compared to conventional dense k-space sampling. However, in most works, each D...
