In this study, the accuracy and precision of vessel area assessment is compared between experts and an automatic full-width at half-maximum method. Both phantom and clinical data is assessed by these two approaches. The experts had fixed display settings and used caliper and contour measurement tools to obtain the vessel cross-sectional area on a predefined location. Our results indicate that the automatic method outperforms the experts on accuracy and precision in the phantom data. The contour measurements are more accurate than the caliper measurements. For the clinical data, the agreement between users and automatic method increases with increasing vessel diameter.
