Introduction: Stroke ranks among the world's major causes of mortality and disability, often linked to carotid artery atherosclerosis. Non-invasive imaging techniques such as colour Doppler sonography provide valuable insights into the carotid arterial system.

Objectives: To assess the carotid artery system in stroke patients with colour Doppler sonography, with an emphasis on carotid stenosis, plaque morphology, and intima-media thickness (IMT).

Methods: This observational research included 50 stroke patients from a tertiary care hospital. Colour Doppler sonography was performed to measure IMT, Assess the degree of carotid stenosis and categorise the structure of the plaque.

Results: Majority of carotid arteries had <50% stenosis. Older age linked to greater stenosis and IMT. Color Doppler imaging is effective for screening carotid artery disease.
