IMT shows lowest variability for carotid atherosclerosis; supports its monitoring role but leaves open 3DUS/MRI standardization in moderate disease.
How do B-mode ultrasound, 3-dimensional ultrasound, and magnetic resonance imaging compare in terms of intraobserver and interscan variability for measuring carotid atherosclerosis in patients with moderate disease?
B-mode ultrasound-derived IMT provides the highest reproducibility, while 3DUS and MRI measurements of vessel wall volume offer high sensitivity and reliability for assessing carotid atherosclerosis.
