Combination of Compressed Sensing and Parallel Imaging with Respiratory Motion Correction for Highly-Accelerated First- Pass Cardiac Perfusion MRI
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...
متن کاملAccelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...

متن کاملA Free-Breathing Approach to High-Resolution Magnetic Resonance Imaging of Myocardial Perfusion: Fully Automated Motion Compensation with Navigators and Highly Accelerated Imaging Using k-t PCA
Cardiovascular magnetic resonance (CMR) imaging has emerged as an important research tool for studies of ischemic heart disease due to its versatility, relatively low cost, and high image quality that allows accurate and reproducible quantification of cardiac structure and function. However, while imaging of cardiac function and myocardial viability (and to some extend imaging of the coronary a...
متن کاملMotion-corrected compressed-sensing enables robust spiral first-pass perfusion imaging with whole heart coverage
Background First-pass perfusion imaging using CMR is an important tool for diagnosing coronary artery disease (CAD), but most clinical techniques are limited in their spatial coverage. While compressed-sensing (CS) holds promise for highly accelerated perfusion spiral imaging, CS techniques suffer from blurring artifacts in the setting of respiratory motion. Spiral pulse sequences have multiple...
