An Evidence-Based Approach to the Efficient Use of Computed Tomography Imaging in the Neurosurgical Patient

Abstract

The probability of discovering a clinically significant finding varies widely for each of the listed study indications. This prospective analysis of all CT scans ordered at a single institution suggests that imaging studies obtained without a change in neurological status were unlikely to produce a positive finding, and even when there was a positive finding, it was extremely unlikely to result in any intervention.
