Compartmental Tissue Characterization using NMR Relaxometry
(2009-04-20)
Magnetic resonance imaging (MRI) is unique in its sensitivity to a wide array of contrast mechanisms in soft tissue. Unfortunately, the physiological and/or microanatomical characteristics that give rise to this contrast ...
Towards quantitative measurements of tissue microstructure using temporal diffusion spectroscopy
(2015-07-06)
Diffusion MRI provides a non-invasive means to characterize tissue microstructure at varying length scales. Apparent diffusion coefficients (ADCs) of tissue water may be measured at relatively long diffusion times with ...
Radiofrequency pulses for improved simultaneous multislice magnetic resonance imaging
(2015-05-22)
Simultaneous multislice (SMS) imaging is a scan acceleration method where mul- tiple slices are simultaneously excited using a multiband pulse and the aliased slice images are separated in reconstruction using the receive ...
Advancements of MRI Measurements of Bound and Pore Water Concentration of Cortical Bone for Evaluation of Fracture Risk
(2016-06-01)
The current standard for diagnosing fracture risk comprises measurements of bone mineral density (BMD), primarily by dual-energy X-ray absorptiometry (DXA). However, bone strength is affected by many factors other than ...
Neural Correlates of Obesity: Disgust, Inflammation, and Brain Function
(2016-06-06)
Body weight is tightly controlled by the homeostatic feeding system, which is primarily reliant upon communication between the endocrine system and the brain. The endocrine system and brain are highly complex systems with ...
