Figure 4.

An APTw image example of non-optimal image quality of normal parotid gland. A 49-year-old male was found with a normal parotid gland of the right side on T2WI (A). On APTw image (B), the integrity was scored as 3, which indicates a lower confidence of the APT value (compared to Figures 2 and 3) with an integrity score 4). Although the hyperintensity artifacts scores were 4, the parotid gland image was considered as being in the evaluable group. The average 3D APTw value of the lesion was −0.94% in ROI_w2. The arrows mean APTw values in ROI.
