Introduction: Hemorrhage volume affects the risk of developing complications after aneurysmal subarachnoid hemorrhage (aSAH). This is quantified subjectively through Fisher Scale. We developed an automated method to quantify intracranial and determine aSAH. Methods: CT scans patients with aSAH were analyzed. An image-processing algorithm was designed in MATLAB volume. The region-growing 3D k-means clustering. Two independent raters manually measured volumes using PACS correlated these measurements ten patients. Vasospasm hydrocephalus identified chart imaging review. Hydrocephalus adjudicated as ventricular enlargement setting ROC analysis performed evaluate association between blood incidence vasospasm, need for a permanent ventriculoperitoneal (VP) shunt. Results: One hundred forty-one included analysis. intraclass coefficient correlation (ICC) inter-rater agreement 0.988 (p < 0.001). ICC comparing versus manual 0.966 Bland-Altman reported mean difference -3.14 mL measurements. discriminated development vasospasm (AUC = 0.692), 0.775), VP shunt 0.669). Conclusion: associated higher Patients at presentation more likely require objective automatically measure can aid assessing among
