- Rapid time-resolved magnetic resonance angiography via a multiecho radial trajectory and GraDeS reconstructionGregory R Lee
Department of Radiology, School of Medicine, Case Western Reserve University University Hospitals of Cleveland, Cleveland, Ohio 44106, USA
Magn Reson Med 69:346-59. 2013..A larger number of iterations improves the temporal behavior at cost of decreased image signal-to-noise ratio. The resulting images provide a good depiction of the cerebral vasculature and have excellent arterial/venous separation...
- Time-efficient slab-selective water excitation for 3D MRIGregory R Lee
Department of Radiology, School of Medicine, Case Western Reserve University University Hospitals of Cleveland, Cleveland, Ohio, USA
Magn Reson Med 67:127-36. 2012..Slab-selective water excitation pulses with durations of 4.1 and 9.2 ms (fractional transition widths of 0.14 and 0.073, respectively) are demonstrated at 4 T...
- Rapid 3D radial multi-echo functional magnetic resonance imagingGregory R Lee
Department of Radiology, School of Medicine, Case Western Reserve University University Hospitals Case Medical Center, Cleveland, Ohio 44106, USA
Neuroimage 52:1428-43. 2010..Weighted combination of the echoes results in Z-scores that are significantly (p=0.016) higher than those resulting from any of the individual echo time images...
- Three-dimensional through-time radial GRAPPA for renal MR angiographyKatherine L Wright
Department of Biomedical Engineering, Case Western Reserve University, Cleveland, Ohio, USA
J Magn Reson Imaging 40:864-74. 2014..In this study, the three-dimensional (3D) through-time radial generalized autocalibrating partially parallel acquisition (GRAPPA) method is used to reconstruct highly accelerated stack-of-stars data for time-resolved renal MRAs...
