Clinical Question
What is the sensitivity of non-contrast head CT for detecting spontaneous subarachnoid hemorrhage (SAH), when performed on a third-generation CT scanner within 6 hours of headache onset?
Conclusion
Third-generation non-contrast head CT is highly sensitive for detecting spontaneous SAH when performed within 6 hours of headache onset and interpreted by either by a radiologist experienced in reading head CT.
