Objective: To determine diagnostic accuracy of angiographic computed tomography (CTA) for detecting intracranial aneurysms in patients with spontaneous subarachnoid hemorrhage (SAH) taking digital subtraction angiography (DSA) as gold standard Design: Cross sectional study Patients and Methods: A total of 195 patients with spontaneous subarachnoid hemorrhage were included in this study. Angiographic computed tomography was done and DSA was used as gold standard. The findings seen on CTA were documented with the help of Performa. Results: The mean age of the patients was 49.01±10.86 years. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of Angiographic computed tomography in detection of intracranial aneurysms was 86.67, 93.33%, 95.41%, 81.4% and 89.23% respectively. Conclusion: In conclusion, spiral CTA is a highly sensitive, specific, fast and non-invasive imaging method for diagnosis and evaluation of aneurysms in cases with acute SAH with suspected intracranial aneurysms.
