Development Of Magnetic Particle Imaging For Quantitative Immune Cell Tracking, Julia J. Gevaert
Electronic Thesis and Dissertation Repository
The Foster lab has been developing cellular MRI tools for well over a decade using superparamagnetic iron oxide (SPIO)-based contrast agents for numerous applications cell tracking applications. SPIO are used to label cells which are indirectly detected as regions of signal loss. The main challenge with this technique is quantification of cell number, which is important for applications such as dendritic cell (DC)-based immunotherapies where cell number is used as a predictor of immunotherapeutic response.
Magnetic particle imaging (MPI) is a novel pre-clinical modality that shows promise for cell tracking. MPI directly detects the nonlinear magnetization response of superparamagnetic iron …

In Vivo Multi-Modal Imaging Approaches For Cancer, Stem And Immune Cells, Nourhan Shalaby
Electronic Thesis and Dissertation Repository
Introduction: Molecular imaging allows for non-invasive longitudinal visualization of cellular functions in vivo. This area of research has provided better understanding of fundamental molecular and biochemical processes, enabled optimization of pre-clinical and clinical assessments for new treatments, and allowed for more accurate and early detection of many pathologies. Extensive research for novel imaging techniques and emerging technologies have rapidly advanced the field. However, an ideal single imaging modality or approach does not exist. Alternatively, multi-modal imaging approaches are commonly applied to overcome limitations of individual technologies. In this thesis, we design, develop, validate, and image various cell types using …
