B-mode ultrasonography shows poor inter-reader agreement for carotid ulceration; this Level 4 evidence leaves open its reliability versus angiography in practice.
How does the measurement variability of carotid B-mode ultrasonography compare to angiography for assessing carotid atherosclerosis?
Angiography provides more reproducible measurements of carotid atherosclerosis than B-mode ultrasonography, particularly for between-reader agreement on ulceration.
O’Leary et al. (1987) studied this question.
