Supports reliable CCA IMT use in vascular protocols; leaves open its added value for risk stratification or outcomes.
Observational (n=30)
The described ultrasound method for estimating common carotid artery IMT provides reproducible and reliable measurements suitable for routine practice.
Sidhu et al. (1997) conducted an observational in Healthy volunteers (n=30). Measurement of intimal-medial thickness of the common carotid artery was evaluated on Reproducibility of IMT measurement (mean absolute difference, coefficient of variation, and coefficient of repeatability). Measurement of common carotid artery intimal-medial thickness was highly reproducible, with an interobserver mean absolute difference of 0.0480 mm and a coefficient of variation of 8.98%.
