Abstract

This study is devoted to a comparative analysis of the effectiveness of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of acute stroke. Analysis of high-impact scientific literature published between 2015 and 2026 demonstrated that non-contrast CT plays a decisive role in the rapid exclusion of intracranial hemorrhage, with a diagnostic accuracy of 95–100%. In contrast, diffusion-weighted MRI (DWI) shows superiority over CT in the early detection of ischemic changes, achieving sensitivity rates of 90–99%. CT and MRI perfusion technologies have enabled a transition from the concept of the “time window” to the “tissue window,” thereby improving the effectiveness of reperfusion therapy. In conclusion, the integration of multimodal neuroimaging and artificial intelligence algorithms represents a strategic approach that optimizes the diagnostic accuracy of stroke and improves patient prognosis.
