Investigates tissue time-to-maximum analysis for assessing delayed cerebral ischemia risk in aneurysmal subarachnoid hemorrhage, suggesting enhanced diagnostic precision.
Perfusion computed tomography predicts and diagnoses delayed cerebral ischemia after subarachnoid hemorrhage, but challenges in precision and interpretation limit its adoption. This study investigated whether tissue time-to-maximum analysis during the peak term of cerebral vasospasm, processed via Rapid Processing of Perfusion and Diffusion, can stratify delayed cerebral ischemia risk in patients with subarachnoid hemorrhage.
