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,...

The popularity of magnetic resonance imaging (MRI) owes much to its flexibility. Sensitive to a host of different biophysical phenomena, parameters of the scan can be fine-tuned to highlight specific pathologies. One such mechanism for generating image contrast is magnetic susceptibility—the...

Transverse relaxation (T2)-weighted images are routinely acquired in clinics. However, T2 quantification is rarely performed as most of the specialized pulse sequences used to quantify T2 are time consuming and thus generally not used in a clinical setup. Nevertheless, there is strong interest in...

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...

Preamplifier Noise Figure Measurement and Radio Frequency Field Optimization in High Field Magnetic Resonance Imaging
DownloadFall 2013
High field magnetic resonance imaging (MRI) is an area of research interest due to the associated improvement in image quality possible. This improvement comes at a cost. Hardware design becomes more complex in order to overcome technical challenges at these higher field strengths....
