Guidelines for cIMT/CP measurement are influenced by major factors like the (i) atherosclerosis disease itself, (ii) conventional risk factors, (iii) 10-year measurement tools, (iv) types of CVD/Stroke risk calculators, (v) incomplete validation of measurement tools, and (vi) the fast pace of computer technology advancements. These articles have shown variable results, which likely reflect a lack of standardization in the (i) tools for measurement, (ii) risk stratification, and (iii) risk assessment. Over 2000 articles have been published that cover either (a) use cIMT/CP or alterations of cIMT/CP and (b) additional image-based phenotypes to associate cIMT related markers with CVD/Stroke risk. J Clin Ultrasound, 2016.Ĭarotid intima-media thickness (cIMT) and carotid plaque (CP) currently act as risk predictors for CVD/Stroke risk assessment. Carotid IAD was more strongly correlated to PS than carotid LD in this population sample of Japanese diabetic patients.

Our automated measurement system gave satisfying results in comparison with manual measurements. The precision of merit of automated versus the two manual measurements was 96.6% and 97.2% for LD, and 97.7% and 98.1%, for IAD, respectively. After excluding 10 outliers, coefficient of correlation was 0.25 (p < 0.0001) between LD and PS, and 0.38 (p < 0.0001) between IAD and PS. The coefficient of correlation was 0.19 (p < 0.007) between LD and PS, and 0.25 (p < 0.0006) between IAD and PS. PS was computed by adding the maximal thickness in millimeters of plaques in segments taken from the internal carotid artery, bulb, and common carotid artery on both sides.
LD and IAD were computed automatically using an advanced computerized edge detection method and compared with two distinct manual measurements. Retrospective study on a database of 404 common carotid artery B-mode sonographic images from 202 diabetic patients. To compare the strength of correlation between automatically measured carotid lumen diameter (LD) and interadventitial diameter (IAD) with plaque score (PS).
