Journal ArticleDOI
New modeling and experimental framework to characterize hindered and restricted water diffusion in brain white matter
TL;DR: A theoretical framework is proposed that combines hindered and restricted models of water diffusion (CHARMED) and an experimental methodology that embodies features of diffusion tensor and q‐space MRI that shows promise in determining the orientations of two or more fiber compartments more precisely and accurately than with diffusion Tensor imaging.
Journal ArticleDOI
Detection of microscopic anisotropy in gray matter and in a novel tissue phantom using double Pulsed Gradient Spin Echo MR.
Michal E. Komlosh,Ferenc Horkay,Raisa Z. Freidlin,Uri Nevo,Yaniv Assaf,Yaniv Assaf,Peter J. Basser +6 more
TL;DR: A double Pulsed Gradient Spin Echo MR experiment was used to measure and assess the degree of local diffusion anisotropy in brain gray matter, and in a novel "gray matter" phantom that consists of randomly oriented tubes filled with water.
Journal ArticleDOI
Real-time three-dimensional echocardiography for measurement of left ventricular volumes.
Michael A. Schmidt,Chikai J. Ohazama,Kwabena O. Agyeman,Raisa Z. Freidlin,Michael Jones,Joy M. Laurienzo,Cynthia L. Brenneman,Andrew E. Arai,Olaf T. von Ramm,Julio A. Panza +9 more
TL;DR: LV volume measurements with RT3D echo are accurate and reproducible and this technique expands the use of ultrasound for the noninvasive evaluation of cardiac patients and provides a new tool for the investigational study of cardiovascular disease.
Journal ArticleDOI
Observation of microscopic diffusion anisotropy in the spinal cord using double-pulsed gradient spin echo MRI.
TL;DR: Using d‐PGSE filtered MRI, microscopic anisotropy was observed in a “gray matter” phantom consisting of randomly oriented tubes filled with water, as well as in fixed pig spinal cord, within a range of b‐values that can be readily achieved on clinical and small animal MR scanners.
Journal ArticleDOI
Mapping average axon diameters in porcine spinal cord white matter and rat corpus callosum using d-PFG MRI.
Michal E. Komlosh,Evren Özarslan,Evren Özarslan,Martin J. Lizak,I. Horkayne-Szakaly,Raisa Z. Freidlin,Ferenc Horkay,Peter J. Basser +7 more
TL;DR: Double-pulsed field gradient filtered MRI was used to map the average axon diameter in porcine spinal cord, which was then compared to AADs measured with optical microscopy of the same specimen, as a way to further validate this new MRI method.
