What is expected of CT in the evaluation of stroke?
This study was based on 5042 cranial CT examinations in a 2-year period. 19.8% of all cranial CT scans were performed for confirmation or evaluation of clinically suspected stroke. 87% of the clinical diagnoses of stroke were confirmed by CT scan. Intracranial hemorrhage made up a small percentage in this study. The establishment of this diagnosis was a valuable service in the patients' management. Brain tumor may rarely present clinical symptoms mimicking stroke and may have a normal CT initially.
