Carotid atherosclerosis is a major cause of stroke, traditionally diagnosed late. Positron emission tomography/computed tomography (PET/CT) with 18F‐sodium fluoride (NaF) detects arterial wall micro‐calcification long before macro‐calcification becomes detectable by ultrasound, CT or magnetic resonance imaging. However, manual PET/CT processing is time‐consuming and requires experience. We compared a convolutional neural network (CNN) approach with manual segmentation of the common carotids.
