Aims and objectives: - Stroke is the third most frequent cause of deaths after cardiovascular diseases and cancer [1,2]. - Ischemic stroke is defined as an event characterized by the sudden onset of acute focal neurologic deficit presumably attributable to cerebral ischemia after exclusion of hemorrhage by CT. Prognosis[...]

Methods and materials: Methods and materials: - The baseline CT scans of 64 acute stroke patients were retrospectively evaluated with respect to early CT findings. This included findings on noncontrast CT, perfusion defects seen on perfusion maps and angiographic findings of vascular occlusion as an etiology to the ischem[...]

Results: - Sixty-four patients with a clinial and radiological diagnosis of stroke who underwent baseline CT stoke protocol were included in the study. The time interval between the onset of symptoms and the intial CT scan ranged from 2 to 6h, and the median time was 3h. - Examination time for the whole stud[...]

Conclusion: Conclusion: - Computed tomography perfusion and CTA provide effective diagnostic tools in acute stroke. Even if Quantitative analysis is not used, the sensitivity to detect acute cerbral infarction is significantly increased compared with native CT alone. An advanced CT protocol including CT perfusi[...]
