title: Problems in magnetic resonance imaging of patients with severe brain injury and a solution to one of them.
abstract: A number of difficulties have been encountered in carrying out MRI scans with severely brain-injured subjects. One of the problems is maintenance of head position for the 30 minutes' duration of the scan. The use of a vacuum cushion has proved a low-cost solution to this problem.
