Brief Summary
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.
Eligibility Criteria
Inclusion Criteria: * Adults aged 18 years or older. * Clinically diagnosed ischemic stroke or transient ischemic attack (TIA). * Imaging performed within 7-14 days of symptom onset. * Hemodynamically stable and suitable for magnetic resonance imaging (MRI). * Able and willing to provide written informed consent. Exclusion Criteria: * Hemorrhagic stroke. * Previous carotid artery stenting. * Contraindications to MRI, including: * Non-MRI-compatible pacemakers or other MRI-incompatible implants. * Cochlear implants. * MRI-incompatible metallic orthopedic implants. * Severe claustrophobia.
