Time Efficient Multi-Pulsed Field Gradient (mPFG) MRI Without Concomitant Gradient Field Artifacts

Abstract: Measuring and mapping nervous tissue microstructure noninvasively is a long sought-after goal in neuroscience. Clinically, several neuropathologies such as cancer and stroke, are associated with changes in tissue microstructure. Diffusion tensor imaging (DTI), which models diffusion anisotropy, is an ideal imaging modality to elucidate these...

Denoising of Dynamic Magnetic Resonance Spectroscopic Imaging Using Low Rank Approximations in the Kinetic Domain

Abstract: Accurate measurement of low metabolite concentrations produced by medically important enzymes is commonly obscured by noise during magnetic resonance imaging (MRI). Measuring the turnover rate of low-level metabolites can directly quantify the activity of enzymes of interest, including possible drug targets in cancer and other diseases. Noise...

Tamperless Tensor Elastography Imaging

Abstract: Measuring and mapping nervous tissue microstructure noninvasively is a long sought-after goal in neuroscience. Several neuropathologies – such as cancer and stroke – are associated with changes in tissue microstructure. Changes in material properties, such as stiffness, represent a sensitive measure of underlying changes in tissue architecture,...

MRI-Based Method for Characterizing Axonal Microstructure in Traumatic Brain Injury

Abstract: Neurites of the central nervous system can be conceptualized as cylindrical pores with finite lengths and radii. In response to physical trauma, axons may assume a “beaded” morphology which alters their ability to conduct electrical impulses, impairing brain function. These microstructural changes are thought to underlie some of the cognitive...

Methods of Determining Homeostatic Perturbations

Abstract: Biological homeostasis is a state of steady internal, physical, and chemical conditions maintained by a living organism observed at the cellular level. Biological homeostasis can vary in order to alter the cellular physical and chemical conditions. Thus, it acts as a mechanism to define the physiological state of cellular activity; for instance...

Quantitative In Vivo Methods for Measuring Brain Networks

Abstract: The pattern or latency connectome was hypothesized to change in physiological development and disease. For example, in amyotrophic lateral sclerosis (ALS), large diameter axons are damaged selectively – while in autism, small-diameter axons may be over-expressed. These anatomical changes are expected to alter the latency connectome or pattern...

Multidimensional MRI Signature for Specific Detection of Traumatic Brain Injury In Vivo

Abstract: Traumatic brain injury (TBI) represents a major medical, social and economic concern worldwide due to significant mortality – especially among younger populations – and long-term disabilities. Various pathological brain lesions (e.g., intracerebral bleedings, necrotic-ischemic lesions, tissue avulsion) are produced by impacting mechanical...
