Spatially Selective 2D RF Inner Field of View (iFOV) Diffusion Kurtosis Imaging (DKI) of the Pediatric Spinal Cord
… evidence that Diffusion Kurtosis Imaging (DKI) can provide additional information about the micromolecular environment of the pediatric spinal cord by more completely characterizing the probabilistic nature of random water displacement. A novel DKI imaging sequence based on a 2D spatially …

Magnetic Resonance imaging of tumour biomarkers in ovarian cancer
… of ovarian cancer. Diffusion kurtosis imaging (DKI), sodium MRI, magnetization transfer (MT) imaging, hyperpolarized carbon-13 MRI and magnetic resonance fingerprinting (MRF) were employed to image ovarian tumours in human subjects. The results of the imaging were compared to semi-quantitative …

The Effects of Youth Football on the Developing Brain: A Multi-Modal Neuroimaging Study
… techniques, such as diffusion kurtosis imaging (DKI) and magnetoencephalography (MEG), can reveal subtle changes in brain structure and function caused by RHI. Our long-term goal is to expand this work and develop a novel neuroimaging-based monitoring protocol for both subconcussive and …

Advanced Methods for Diffusion MRI Data Analysis and their Application to the Healthy Ageing Brain
… provided by the diffusion kurtosis imaging (DKI) technique is explored and used to resolve crossing fibres and generalize diffusion measures to cases not limited to well-aligned white matter fibres. Thirdly, as an alternative to diffusion microstructural modelling techniques such as the …

Validation of magnetic resonance imaging (MRI) as a tool to detect inflammation in the brain
… Alterations to diffusion kurtosis imaging (DKI) parameters were observed in regions including the fornix and sagittal stratum. Voxel-wise analysis of QMT parameters indicated an inflammatory-mediated cerebellar increase in magnetization transfer exchange rate that correlated with decreased …

Quantitative Dwi As An Early Imaging Biomarker of The Response to Chemoradiation In Esophageal Cancer
<p>For patients diagnosed with stages IIa-IIb esophageal cancer, the current standard of care treatment is tri-modality therapy (TMT), where neoadjuvant chemoradiation (nCRT) is followed by surgical resection. Histopathology of resected tumors reveals that pathological complete response (pCR) is …
