SUMMARY
A good quality scan will detect SAH > 95% if the case is scanned within 48hrs of the ictus. CT can also assess the following:
1. Hydrocephalus: occurs acutely in 21% of ruptures
2. Hematoma: intraparenchymal or subdural which may require urgent evacuation
3. Amount of blood in the subarachnoid space: this is an important prognosticator for vasospasm
4. In multiple aneurysms, CT can identify which one bled
5. Non-contrast CT can predict aneurysm location in 70% of cases
