Assessment of distribution and evolution of mechanical dyssynchrony in a porcine model of myocardial infarction by cardiovascular magnetic resonanceKhaled Z Abd-Elmoniem
Biomedical and Metabolic Imaging Branch, National Institute of Diabetes and Digestive and Kidney Diseases, NIH, Bethesda, MD, USA
J Cardiovasc Magn Reson 14:1. 2012..We sought to investigate the relationship between infarct and dyssynchrony post- myocardial infarct (MI), in a porcine model. Mechanical dyssynchrony post-MI is associated with left ventricular (LV) remodeling and increased mortality...
Simultaneous quantitative cerebral perfusion and Gd-DTPA extravasation measurement with dual-echo dynamic susceptibility contrast MRIE P Vonken
Image Sciences Institute, University Hospital Utrecht, Utrecht, The Netherlands
Magn Reson Med 43:820-7. 2000..It is applicable whether extravasation occurs or not. When extravasation is present, application of the proposed method is mandatory for accurate cerebral blood volume measurements. Magn Reson Med 43:820-827, 2000...
On the dual contrast enhancement mechanism in frequency-selective inversion-recovery magnetic resonance angiography (IRON-MRA)Evert Jan Vonken
Russell H Morgan Department of Radiology and Radiological Science, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA
Magn Reson Med 62:314-24. 2009..First results obtained in an in vivo rabbit model are presented...
Positive contrast visualization of nitinol devices using susceptibility gradient mappingEvert jan P A Vonken
Russell H Morgan Department of Radiology and Radiological Science, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA
Magn Reson Med 60:588-94. 2008..The positive signal response of this method depends only on the choice of the voxel neighborhood size. The properties of the method are explained and the visualizations of a nitinol wire and two stents are shown for illustration...
Positive contrast visualization of iron oxide-labeled stem cells using inversion-recovery with ON-resonant water suppression (IRON)Matthias Stuber
Russell H Morgan Department of Radiology and Radiological Science, Division of MR Research, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21287, USA
Magn Reson Med 58:1072-7. 2007..The first successful use of IRON to produce positive contrast in areas of metallic spheres and SPIO-labeled stem cells in vitro and in vivo is presented...
Automatic segmentation of intracranial arteries and veins in four-dimensional cerebral CT perfusion scansAdriënne Mendrik
Image Sciences Institute, University Medical Center Utrecht, Heidelberglaan 100, 3584 CX Utrecht, The Netherlands
Med Phys 37:2956-66. 2010..An additional CT perfusion (CTP) scan is acquired of these patients to assess the perfusion of the cerebral tissue. The aim of this study is to extend the diagnostic yield of the CTP scans to also include vascular information...
Improved SNR efficiency in gradient echo coronary MRA with high temporal resolution using parallel imagingJing Yu
Russell H Morgan Department of Radiology and Radiological Science, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21287, USA
Magn Reson Med 62:1211-20. 2009..This method is most suitable for spoiled gradient echo coronary magnetic resonance angiography in which a high temporal and spatial resolution is required...
TIPS bilateral noise reduction in 4D CT perfusion scans produces high-quality cerebral blood flow mapsAdriënne M Mendrik
Image Sciences Institute, University Medical Center Utrecht, Heidelberglaan 100, 3584 CX Utrecht, The Netherlands
Phys Med Biol 56:3857-72. 2011..Furthermore, the TIPS bilateral filter is computationally faster than both the 3D and 4D bilateral filters...
