Which patient characteristics and investigations are most accurate for diagnosing subarachnoid hemorrhage?

BEEM Bottom Line

Why is this study important?

Traditional medical education espouses the routine use of non-contrast computed tomography (NCCT) of the head and lumbar puncture (LP) together to evaluate all patients suspected of having a subarachnoid hemorrhage (SAH).
