Moderate reproducibility of subjective carotid plaque grading warrants clinical caution; leaves open need for objective methods or standardization.
What is the intraobserver and interobserver variability of subjective grading of carotid plaque morphology from ultrasound images?
Subjective ultrasound characterization of carotid plaque morphology has variable reproducibility, which may be improved by using simpler 2-category grading on digital images.
Arnold et al. (1999) studied this question.
