Official title: Comparison Between Non-contrast Magnetic Resonance Angiography and Carotid Doppler in Cerebrovascular Stroke
Run by Sohag University · NCT07756775 · Data updated 2026-11-12
This study tests whether non-contrast MRA can match or improve upon carotid Doppler in finding and grading carotid artery narrowing in adults with ischemic stroke or TIA.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older with a clinically diagnosed ischemic stroke or TIA, imaged within 7–14 days of symptom onset, who are stable and eligible for MRI.
✕Probably not a fit
Patients with contraindications to MRI or severe claustrophobia, or those with prior carotid stenting, may not benefit from NC-MRA in this study.

What this trial studies
This prospective observational study enrolls 200 adults with ischemic stroke or TIA to compare non-contrast magnetic resonance angiography (NC-MRA) and carotid Doppler ultrasonography for detecting and grading carotid stenosis using NASCET criteria. Each participant undergoes both imaging tests within 7–14 days of symptom onset, and results are analyzed for agreement and clinical utility. The goal is to determine how well NC-MRA performs relative to Doppler and to inform imaging strategies for cerebrovascular assessment. The study is conducted at Sohag University Hospital with Sohag University as the lead sponsor.
Why it matters
Potential benefit: If successful, NC-MRA could provide an alternative imaging option that complements or replaces Doppler in certain patients, potentially streamlining diagnosis and management.
How similar studies have gone: Prior work comparing imaging modalities for carotid stenosis supports usefulness of noninvasive MRI approaches, though direct head‑to‑head data with NC-MRA vs Doppler in this exact context remains limited.
