- Original description
This prospective observational study aims to compare the diagnostic performance of non-contrast magnetic resonance angiography (NC-MRA) and carotid Doppler ultrasonography in the evaluation of carotid artery disease among patients with ischemic cerebrovascular stroke or transient ischemic attack. A total of 200 adult patients presenting to Sohag University Hospital will undergo both imaging modalities. The study will assess the agreement between NC-MRA and carotid Doppler in detecting and grading carotid artery stenosis according to the NASCET criteria, with the goal of evaluating the clinical utility of each technique and optimizing imaging strategies for the assessment of cerebrovascular stroke.Read full original descriptionShow less
