Magnetic resonance imaging of ligaments and membranes in the craniocervical junction in whiplash-associated injury and in healthy control subjects.

Background: The pathogenesis and imaging findings in whiplash-associated injury (WAD) are poorly understood and remain debatable.

Purpose: To assess the ligaments and membranes in the craniocervical junction with magnetic resonance imaging (MRI) in patients with WAD and to compare them with healthy control subjects.

Material And Methods: Twenty-eight patients with WAD were selected at random from a total number of 180 examined with MRI using 2-mm proton density (PD)-weighted images in three orthogonal planes at 1.

[Diagnostic imaging techniques in the investigation of dementia].

Background: Neuroimaging can provide valuable information in the diagnostic work-up of patients presenting with suspected dementia.

Material And Methods: Based on our experience from a memory clinic at Ullevål University Hospital in Oslo, Norway and on relevant literature identified on Medline, we give an overview of the use of neuroimaging methods in patients with suspected dementia.

Results And Interpretation: CT of the brain should be offered to all patients with suspected dementia as CT can provide essential diagnostic information regarding focal cerebral pathology (tumour, haemorrhage, normal pressure hydrocephalus).
