Detection of pseudodiarrhoea by simple clinical assessment of intestinal transit rate.
LJ O'Donnell, J Virjee, KW Heaton - BMJ: British Medical Journal, 1990 - ncbi.nlm.nih.gov
Cervical intraepithelial neoplasia is common in young symptomless women. Such women
often believe that the function of a smear test is to detect cancer rather than to prevent it.'…

Automatic tractography segmentation using a high-dimensional white matter atlas
LJ O'Donnell, CF Westin - IEEE transactions on medical …, 2007 - ieeexplore.ieee.org
We propose a new white matter atlas creation method that learns a model of the common
white matter structures present in a group of subjects. We demonstrate that our atlas creation …

Q-space trajectory imaging for multidimensional diffusion MRI of the human brain
…, D van Westen, C Mattisson, M Bogren, LJ O'Donnell… - Neuroimage, 2016 - Elsevier
This work describes a new diffusion MR framework for imaging and modeling of microstructure

Tract-based morphometry for white matter group analysis
We introduce an automatic method that we call tract-based morphometry, or TBM, for
measurement and analysis of diffusion MRI data along white matter fiber tracts. Using subject-…
