Accelerated resting-state functional magnetic resonance imaging (R-fMRI) can provide higher spatial resolution and improved brain connectivity maps. Current methods for fast R-fMRI rely on either fully-sampled parallel imaging or undersampled reconst

In high-angular-resolution diffusion imaging (HARDI), simultaneous multislice (SMS) acquisition incorporated in multi-coil parallel imaging offers speedups in addition to the speedup obtained from undersampling gradient directions. We propose a novel

High-angular-resolution diffusion imaging (HARDI) relies on multicoil acquisitions for clinical applications. HARDI scan time can be reduced by undersampling the set of gradient directions. Typical methods for undersampled HARDI reconstruction use tw

Simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) provide complementary information about brain function and structure. Joint reconstruction of MRI and PET images can improve image quality in both modalities, potent

High angular resolution diffusion imaging (HARDI) at higher b values leads to signal measurements having (exponentially) lower magnitudes, a strong Rician bias, and more corruptions from artifacts. Typical undersampled-HARDI reconstruction methods as

This paper presents a new compressed sensing framework for multishell HARDI. Unlike methods that model diffusion signals using analytical bases, we learn a dictionary of multishell diffusion signals, with a proposed regularization term to handle low
