Abstract
Diffuse axonal injury (DAI), associated with deafferentation and functional rearrangement, probably plays a role in the chronic phase of traumatic brain injury (TBI). DAI with a haemorrhagic component can be quantified using magnetic resonance imaging (MRI) thanks to the iron-based susceptibility effect of haemosiderin, which increases with magnetic field strength. The aim of this work was to compare conventional 1.5 Tesla and 3 Tesla MRI in the assessment of DAI in TBI patients. Eighteen TBI patients were submitted, in random order, to a 1.5T and a 3T MRI examination using standard gradient echo sequences. Both scans were always performed on the same day. DAI lesions with a haemorrhagic component were manually segmented and classified by anatomical location. The Wilcoxon and ANOVA tests were used for statistical analysis, significance being set at p
