Computed tomographic (CT) head scans were performed on 100 patients in a neurology ward. The CT scan was diagnostic in 67 patients and suggestive in a further three patients. Computed tomographic scans were most likely to be diagnostic in patients whose symptoms at presentation could be classified as “traumatic intracranial lesion”, “space‐occupying lesion”, “acute cerebrovascular lesion”, “dementia”, and “epileptic disorder”, and much less likely to be diagnostic if a patient presented differently. In all cases where the CT scan was diagnostic, it was considered that, had a CT scan not been available, alternative tests such as nuclear scan, cerebral angiography or pneumoencephalogram (PEG) would have been performed and would also have been diagnostic; no impact of the CT scan on diagnosis, therapy or patient outcomes was documented. However, in patients who received a CT scan, there was a 91% reduction in the PEGs, 85% reduction in cerebral angiograms, a reduction of 73% in nuclear scans and 31% in electroencephalograms. Computed tomographic scanning costs no more than the tests it replaces in the clinical setting studied, and offers significant advantages in patient comfort and safety.
