Characterizing Dynamic MRI Using Objective Image Quality Metrics
(2017-08-08)Quantitative mapping in dynamic magnetic resonance imaging (MRI) aims to recover quantitative parameters describing properties of patient tissues. However, quantitative mapping in dynamic MRI is difficult due to limitations ... -
Examining Neuroradiologists’ Task-Specific Diagnostic Confidence in Reporting Acute and Chronic Stroke for Retrospectively Accelerated 0.5 T MR Images
(2022-09-01)Accelerated MRI is key for emergency medicine situations like acute ischemic stroke (AIS). Though acceleration alters image quality, neuroradiologists may remain able to report stroke pathology. This thesis examines ... -
INVESTIGATING OFF-RESONANCE FAT MODULATIONS IN THE TURBOSPI SIGNAL TO IMPROVE R2* MAPPING FOR QUANTITATIVE CELL TRACKING
(2017-12-15)Immune cells can be labelled with superparamagnetic iron oxide (SPIO) nanoparticles and detected in vivo. Tracking the migration of immune cells is valuable for understanding the immunogenic response to both cancer and ... -
Multiplexed Sensitivity Encoding of Multi-Shot Diffusion-Weighted Echo Planar MRI at 0.5 Tesla for Cholesteatoma Imaging
(2023-10-27)Cholesteatoma is an abnormal skin mass in the middle ear requiring surgical excision, and accurate post-surgical imaging is of interest to avoid repeat surgeries. MRI suffers from susceptibility-induced field gradients at ... -
Quantitative Magnetic Resonance Imaging of Cellular Density with TurboSPI
(2012-08-14)Magnetic Resonance Imaging can now detect cells that are labeled with contrast agents such as superparamagnetic iron oxide (SPIO). Quantitative monitoring, which is desirable for evaluating cellular therapies, remains ...
