Figure 3

An APTw image example with fairly good lesion image quality. A large lesion of the left parotid gland was found in a 76-year-old male, as shown on T2WI (A). The corresponding APTw image of the same slice is shown in (B). The APT image integrity was scored as 4. The image quality in terms of hyperintensity artifacts was scored as 3, and the APT values in the ROIw1 were elevated by the surrounding hyperintensity artifacts through the smoothing effects. The lesion was considered as being in the trustable group. The average 3D APTw value of the lesion was 4.22% (in ROIw2). The arrows mean APTw values in ROI.
