E.M.I. scan in the management of head injuries

Abstract

The E.M.I. scan has much simplified the management of head injuries. The conventional investigations have been supplanted by a safe non-invasive technique, in which lesions of the brain can be demonstrated. Thus high density intracerebral or extracerebral haematoses are readily diagnosed, even when they are in unusual sites. Wherever their location, they appear in sharp contrast to the low density of cerebral contusions or chronic subdural haematomas. The safety of the procedure recommends its sequential use in patients who fail to improve or who deteriorate; and repeated examinations can be useful in monitoring the response to therapy. Under clinical supervision, the quantity and quality of information the method yields during a single comprehensive study is such that it should became the definitive investigation in the victims of cerebral trauma.
