High-resolution single-shot spiral diffusion-weighted imaging at 7T using expanded encoding with compressed sensing
Gabriel Varela-Mattatall, Paul I. Dubovan, Tales Santini +3
Purpose: The expanded encoding model incorporates spatially- and time-varying field perturbations for correction during reconstruction. So far, these reconstructions have used the…
BMART-Enabled Field-Map Combination of Projection-Reconstruction Phase-Cycled SSFP Cardiac Cine for Banding and Flow-Artifact Reduction
Anjali Datta, Dwight G Nishimura, Corey A Baron
Purpose: To develop a method for banding-free bSSFP cardiac cine with substantially reduced flow artifacts. Methods: A projection-reconstruction (PR) trajectory is proposed for a f…
High-Resolution, Respiratory-Resolved Coronary MRA Using a Phyllotaxis-Reordered Variable-Density 3D Cones Trajectory
Srivathsan P. Koundinyan, Corey A. Baron, Mario O. Malave +6
Purpose: To develop a respiratory-resolved motion-compensation method for free-breathing, high-resolution coronary magnetic resonance angiography using a 3D cones trajectory. Metho…
Unraveling the Effect of Spatial Resolution and Scan Acceleration on 3D Image-Based Navigators for Respiratory Motion Tracking in Coronary MR Angiography
Srivathsan P. Koundinyan, Joseph Y. Cheng, Mario O. Malave +4
Purpose: To study the accuracy of motion information extracted from beat-to-beat 3D image-based navigators (3D iNAVs) collected using a variable-density cones trajectory with diffe…
Diffusion Dispersion Imaging: Mapping OGSE Frequency Dependence in the Human Brain
Aidin Arbabi, Jason Kai, Ali R Khan +1
Purpose: Oscillating gradient spin-echo (OGSE) diffusion MRI provides information about the microstructure of biological tissues via the frequency dependence of the apparent diffus…
