On the Reconstruction of Planar Vector Fields From Its Longitudinal and Transverse Ray Transform

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider a planar vector tomography problem of reconstructing a complex‐valued vector field from the (complete and partial) information of its longitudinal and transverse ray transforms, as well as from one of those transforms and its first moment.

Towards Faster Fetal 3D CINE Cardiac MRI Reconstruction Using Region‐Optimized Virtual Coils (ROVir)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate, in a feasibility study, a computationally efficient image‐reconstruction pipeline for 3D balanced steady state free precession (bSSFP) CINE fetal cardiac MRI that reduces radial streaking artifacts, increases effective temporal resolution, and improves diagnostic image quality compared with previous work ...

QQ‐Based Oxygen Extraction Fraction (OEF) Mapping in Mouse Brain: Initial Experience

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Oxygen extraction fraction (OEF) is a vital biomarker of cerebral oxygen metabolism and tissue viability. A novel OEF mapping method, QQ, which combines quantitative susceptibility mapping (QSM) and quantitative blood oxygen level‐dependent (qBOLD) (QSM + qBOLD = QQ), has demonstrated promise in detecting disease‐related OEF ...

Whole‐Brain Cerebral Microvascular Pulsatility Imaging Using Dynamic pCASL MRI With Segmented Stack‐of‐Stars Golden‐Angle Radial Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an efficient dynamic pseudo‐continuous arterial spin labeling (pCASL) MRI technique for whole‐brain microvascular flow pulsatility imaging. Methods The proposed technique combines pCASL with a segmented stack‐of‐stars golden‐angle radial acquisition.

Prandial Effects on Intravoxel Incoherent Motion Quantification in the Liver

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of detecting prandial (i.e., meal) induced changes in microvascular flow in the liver, including changes in the spatial distribution of flow velocities, using intravoxel incoherent motion (IVIM) MRI. Methods Thirteen (n = 13) healthy volunteers underwent two liver MR exams: one preprandial after fasting and ...
