Advances in Quantitative Susceptibility Mapping for Human Brain: Applications in Hemorrhage, Motion, Blood Vessels
DownloadFall 2022
Quantitative Susceptibility Mapping (QSM) is an emerging postprocessing method, computed from phase images, which is finding wide application in quantifying iron content in healthy and pathological tissue. However, QSM is still not commonly used in clinical practice. This thesis discusses the...

Development and Application of Quantitative Gradient-Echo MRI Techniques for Assessment of Iron and Myelin in the Multiple Sclerosis Brain
DownloadFall 2018
Multiple Sclerosis (MS) is a progressive autoimmune and neurodegenerative disease of the Central Nervous System that results in demyelination and neuronal/axonal loss. Along with clinical evaluation, Magnetic Resonance Imaging (MRI) is the gold standard modality for diagnosing and monitoring MS,...

Quantitative susceptibility mapping (QSM) is an emerging magnetic resonance imaging (MRI) method that provides image contrast based on an important underlying brain tissue property. It is derived from the phase images from a gradient echo sequence, and overcomes the orientation dependency problem...

Quantitative Susceptibility Mapping in Ischemic Stroke: Cerebral Veins, Tissue, and Microbleeds
DownloadSpring 2019
Quantitative susceptibility mapping (QSM) is an emerging magnetic resonance imaging (MRI) post-processing technique that uses phase images from a gradient echo sequence to create magnetic susceptibility maps. QSM is sensitive to paramagnetic iron found in various states of blood, from...
