Harmonization of Brain Diffusion MRI: Concepts and Methods
Frontiers in Neuroscience, 2020 MRI diffusion data suffers from significant inter- and intra-site variability, which hinders multi-site and/or longitudinal diffusion studies. This variability may arise from a range of factors, such as hardware, reconstruction algorithms and acquisition

Whole-body MRI and diffusion MRI [PDF]
Cancer Imaging, 2014 Metastatic bone disease is a common manifestation of advanced cancers with a very high prevalence in breast, prostate and lung cancers. In order to effectively manage patients with metastatic bony disease it is essential to have consistent, reproducible and validated methods for detecting and assessing the response to therapy.

Optimization of diffusion imaging for multiple target regions using maximum likelihood estimation
Current Directions in Biomedical Engineering, 2017 In this work a procedure is proposed to determine an optimal distribution of b-values in diffusion MRI measu-rements. The optimization procedure uses a method of Maximum Likelihood Estimation which can operate on any given number of b-values, values of ...

Deep Diffusion MRI Registration (DDMReg): A Deep Learning Method for Diffusion MRI Registration [PDF]
IEEE Transactions on Medical Imaging, 2021 AbstractIn this paper, we present a deep learning method, DDMReg, for accurate registration between diffusion MRI (dMRI) datasets. In dMRI registration, the goal is to spatially align brain anatomical structures while ensuring that local fiber orientations remain consistent with the underlying white matter fiber tract anatomy.
