A Diffusion MRI Tractography Connectome of the Mouse Brain and Comparison with Neuronal Tracer Data.
(Cereb Cortex, 2015-11)Interest in structural brain connectivity has grown with the understanding that abnormal neural connections may play a role in neurologic and psychiatric diseases. Small animal connectivity mapping techniques are particularly ... -
Automated multimodal segmentation of acute ischemic stroke lesions on clinical MR images.
(Magnetic resonance imaging, 2022-10)Magnetic resonance (MR) imaging (MRI) is commonly used to diagnose, assess and monitor stroke. Accurate and timely segmentation of stroke lesions provides the anatomico-structural information that can aid physicians in predicting ... -
BOLD signal compartmentalization based on the apparent diffusion coefficient.
(Magn Reson Imaging, 2002-09)Functional MRI (fMRI) can detect blood oxygenation level dependent (BOLD) hemodynamic responses secondary to neuronal activity. The most commonly used method for detecting fMRI signals is the gradient-echo echo-planar imaging ... -
Implementing diffusion-weighted MRI for body imaging in prospective multicentre trials: current considerations and future perspectives.
(European radiology, 2018-03)For body imaging, diffusion-weighted MRI may be used for tumour detection, staging, prognostic information, assessing response and follow-up. Disease detection and staging involve qualitative, subjective assessment of images, ... -
Measuring robustness of brain networks in autism spectrum disorder with Ricci curvature.
(Scientific reports, 2020-07-02)Ollivier-Ricci curvature is a method for measuring the robustness of connections in a network. In this work, we use curvature to measure changes in robustness of brain networks in children with autism spectrum disorder (ASD). ... -
POCS-based reconstruction of multiplexed sensitivity encoded MRI (POCSMUSE): A general algorithm for reducing motion-related artifacts.
(Magn Reson Med, 2015-11)PURPOSE: A projection onto convex sets reconstruction of multiplexed sensitivity encoded MRI (POCSMUSE) is developed to reduce motion-related artifacts, including respiration artifacts in abdominal imaging and aliasing artifacts ... -
Quantitative mapping of trimethyltin injury in the rat brain using magnetic resonance histology.
(Neurotoxicology, 2014-05)The growing exposure to chemicals in our environment and the increasing concern over their impact on health have elevated the need for new methods for surveying the detrimental effects of these compounds. Today's gold standard ...
