To introduce a novel magnetic-resonance fingerprinting (MRF) framework with single-shot echo-planar imaging (EPI) readout to simultaneously estimate tissue T2, T1 and T2, and integrate B1 correction. Spin-echo EPI is combined with gradient-echo EPI to achieve T2 estimation as well as T1 and T2 quantification. In the…

To foster the efficient development of 3D cell culture models, we developed a strategy to assess the liquid flow perfusion through biocompatible scaffolds. Biocompatible scaffolds play a crucial role in creating 3D in vitro models for precision medicine. Therefore, it is imperative to thoroughly characterise the…

Subcortical nuclei and other deep brain structures play essential roles in regulating the central and peripheral nervous systems. However, many of these nuclei and their subregions are challenging to identify and delineate in conventional MRI due to their small size, hidden location, and often subtle contrasts compared…

Presently, Magnetic Resonance Imaging (MRI) magnets must deliver excellent magnetic field (B0) uniformity to achieve optimum image quality. Long magnets can satisfy the homogeneity requirements but require considerable superconducting material. These designs result in large, heavy, costly, and unstable systems that…

External beam radiotherapy (XRT) is a widely used cancer treatment, yet responses vary dramatically between patients. These differences are not accounted for in clinical practice, in part due to a lack of sensitive biomarkers of early response. In this work, we test the hypothesis that quantification of intratumor…
