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. 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). 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. 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. Colour Doppler sonography is an effective tool for non-invasive evaluation of carotid arterial system, aiding in early detection and management of carotid artery disease.
