What this trial studies

This observational study aims to evaluate the accuracy of transcranial colour coded duplex (TCCD) in comparison to CT angiography for detecting arterial obstructions in patients who have experienced acute ischemic strokes or transient ischemic attacks. The study focuses on understanding the prevalence of intracranial stenosis and its implications in different ethnic groups, particularly in the Egyptian population, where data is scarce. By assessing the effectiveness of TCCD, the study seeks to provide insights into a potentially less invasive imaging method for stroke diagnosis. The findings could enhance the understanding of stroke mechanisms and improve diagnostic approaches in clinical settings.
