Measuring Dynamic Changes in Lung Water Density and Volume Following Supine Body Positioning Using Free-Breathing UTE MRI
DownloadSpring 2024
An excess of extravascular lung water (EVLW) is known as pulmonary edema, and is associated with dyspnea and poor exercise capacity, heart complications, heart failure, and can be a predictor of poor health outcomes. Recent developments in magnetic resonance imaging (MRI) sequencing and hardware...

Fats are a fundamental building block of the human body, but accumulation of unwanted fat in and around tissues is a common pathology related to many disease mechanisms. Magnetic Resonance Imaging (MRI) offers a host of methods to differentiate water and fat signals in images or spectra, for...

Tracking myelination and demyelination in the brain is a crucial part of studies on neurodegenerative diseases such as Multiple Sclerosis (MS). Classic MRI techniques are unable to provide enough information about the pathology of tracts and lesions. Multi-component analysis of multi-echo data...

Osteoarthritis (OA) is characterized by progressive destruction of articular cartilage, subchondral bone sclerosis, and osteophyte formation. Currently there is no disease modifying drug for treatment of OA. Usually OA is not diagnosed until the advanced stages, where palliative treatment is the...

Osteoarthritis is characterized by pain and inflammation in joints, typically weight-bearing joints such as the knee. An early warning sign of osteoarthritis is the loss of proteoglycan molecules in the cartilage matrix. A surrogate method for measuring proteoglycan loss is detection of sodium...

Oscillating Gradient Spin Echo (OGSE): A Study of Short Diffusion Time Effects in Human Brain at 3T
DownloadSpring 2020
Diffusion-weighted magnetic resonance imaging (DWI) is a non-invasive MRI technique that is sensitive to the diffusion of water molecules within the body. Its ability to encode water displacements enables it to detect changes in neural microstructure, such as those due to normal healthy aging or...

This thesis addresses the challenge of prognosis, in terms of survival prediction, for patients with Glioblastoma Multiforme brain tumors. Glioblastoma is the most malignant brain tumor, which has a median survival time of no more than a year. Accurate assessment of prognostic factors is critical...

Pulmonary edema (PE) involves an excess of extravascular lung water (EVLW) due to an imbalance in fluid filtration which results in hypoxia and respiratory distress. Cardiogenic pulmonary edema is a primary clinical feature and therapeutic target in acute heart failure. Current methods in...

Quantitative Susceptibility Mapping in Human Brain: Short Echo Timing, Thin Slab, and Non-harmonized Multisite Applications
DownloadSpring 2023
Quantifying tissue magnetic susceptibility provides a non-invasive way to monitor iron and myelin abnormalities associated with several neurodegenerative diseases. Quantitative susceptibility mapping (QSM) is a post-processing technique that retrieves the susceptibility distribution from the...
