The SENSE-Isomorphism Theoretical Image Voxel Estimation (SENSE-ITIVE) model for reconstruction and observing statistical properties of reconstruction operators
23 May 2012
Iain P. Bruce, M. Muge Karaman, Daniel B. Rowe
Abstract: The acquisition of sub-sampled data from an array of receiver coils has become a common means of reducing data acquisition time in MRI. Of the various techniques used in parallel MRI, SENSit...

Comparison of dual-echo DSC-MRI- and DCE-MRI-derived contrast agent kinetic parameters
23 May 2012
C. Chad Quarles, John C. Gore, Lei Xu, Thomas E. Yankeelov
Abstract: The application of dynamic susceptibility contrast (DSC) MRI methods to assess brain tumors is often confounded by the extravasation of contrast agent (CA). Disruption of the blood–brain bar...

Compressed sensing MR image reconstruction using a motion-compensated reference
14 May 2012
Huiqian Du, Fan Lam
Abstract: Compressed sensing (CS)-based methods have been proposed for image reconstruction from undersampled magnetic resonance data. Recently, CS-based schemes using reference images have also been ...

Detecting cortical lesions in multiple sclerosis at 7 T using white matter signal attenuation
14 May 2012
Katharine T. Bluestein, David Pitt, Steffen Sammet, Cherian Renil Zachariah, Usha Nagaraj, Michael V. Knopp, Petra Schmalbrock
Abstract: Cortical lesions have recently been a focus of multiple sclerosis (MS) MR research. In this study, we present a white matter signal attenuating sequence optimized for cortical lesion detecti...
