Comparison of non-contrast CT, CT perfusion, and CT angiography for predicting delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage

More straightforward and reliable indicators are required to facilitate early delayed cerebral ischemia prediction. The non-contrast CT model, utilizing admission variables, was most predictive of delayed cerebral ischemia. Non-contrast CT at admission reliably predicts delayed cerebral ischemia risk and severity in most aneurysmal subarachnoid hemorrhage patients.
