Change in average maximum standardized uptake values (aSUVmax) from baseline to follow-up. The black diamonds represent the mean aSUVmax at baseline and follow-up with the 95% confidence interval as the dotted line. Mean difference in aSUVmax of − 0.18, CI95%: − 0.34 to − 0.02, P = 0.034. The light blue lines represent each patient with the circles marking the aSUVmax at baseline and follow-up. The patient with recurrent symptoms undergoing carotid endarterectomy before the follow-up scan is marked as a filled circle
