Figure 8

An APTw image example of a hyperintensity artifact caused by vessels. Image (A) T2WI shows the normal gland of the left side of a 28-year-old female with vessels passing through (white arrows). On the APTw (B) image, the APT image integrity was scored 4. The image quality in terms of hyperintensity artifacts was scored 3 because the APT values in the ROIw1 were moderately affected by the hyperintensity of the vessel (black arrow), while part of normal gland was unaffected (as in ROIw1). The resulting mean APTw value of the parotid gland was 2.63% in ROIw2.
