Comparative diagnostic value of carotid colour Doppler ultrasound and carotid magnetic resonance angiography in detecting carotid artery stenosis

Both CDO and MRA are valuable non-invasive tools for evaluating carotid vascular stenosis. CDO is simple, cost-effective and suitable for large-scale screening, whereas MRA provides detailed vascular anatomy and is better suited for confirmatory assessment of complex lesions. Appropriate selection or combined use can improve diagnostic accuracy and clinical decision-making.
