Czernecki, R. Gupta, F. Gomas, P. Sanchez, D. Dormont, D. Galanaud, R.D. Stevens, L. Puybasset and for NICER (Neuro Imaging for Coma Emergence and Recovery) ConsortiumAmerican Journal of Neuroradiology January 2014, 35 (1) 23-29; DOI: https://doi.org/10.3174/ajnr.A3616
The authors used DTI to study posttraumatic white matter changes over a 5-year period. Thirteen patients with severe injuries acutely showed significant fractional anisotropy decreases in the corpus callosum and corona radiata when compared with controls. These abnormalities progressed at 2 years and then remained stable until 5 years. The DTI abnormalities correlated with sequelae such as amnesia, aphasia, and dyspraxia.

Ramasamy, B. Weinstock-Guttman, J. Hagemeier, C. Kennedy, R. Melia, D. Hojnacki, M. Ramanathan and R. ZivadinovAmerican Journal of Neuroradiology January 2014, 35 (1) 106-112; DOI: https://doi.org/10.3174/ajnr.A3653
Healthy individuals who either had no relatives with multiple sclerosis or had a family history of it were studied and evaluated according the Okuda and Swanton criteria for radiologically isolated syndrome. These investigators found that the frequency of white matter signal abnormalities and radiologically isolated syndrome were higher in the healthy relatives of patients with multiple sclerosis compared with nonfamilial healthy control subjects. In healthy relatives of patients with MS, smoking and obesity also contributed to the presence of white matter lesions.

Royle, S. Muñoz Maniega, B.S. Aribisala, C. Murray, I.J. Deary and J.M. WardlawAmerican Journal of Neuroradiology January 2014, 35 (1) 55-62; DOI: https://doi.org/10.3174/ajnr.A3612
These authors sought to characterize white matter lesions of elderly adults and determine if some were artifacts. Using FLAIR they imaged 665 subjects without dementia, carefully measured and evaluated periventricular white matter lesions, and correlated these with several aspects of cardiovascular disease. They concluded that periventricular white matter hyperintensity levels, distribution, and association with risk factors and disease suggest that in old age, these are true tissue abnormalities and therefore should not be dismissed as artifacts.
