Reducing motion artefacts in diffusion-weighted MRI of the brain: efficacy of navigator echo correction and pulse triggering.

abstract：:We studied serial MRI appearances of transneuronal degeneration in the inferior olives, retrospectively analysing follow-up images of five patients, three with head injury and two with brain stem haemorrhage. We performed 13 MRI studies 4 days to 2 years 7 months after the accident. All but one of the patients exhibit...
