Figure 1. Representative case of a well-differentiated squamous cell carcinoma of the maxilla.

Figure 1

(A) Axial spin–spin relaxation time-weighted image of a metastatic buccinator node (arrow) that shows a large, hyperintense necrotic area. (B) Axial diffusion-weighted echo-planar MR image at b factor of 500 s/mm2, the metastatic node appears hyperintense (arrow). (C) Axial diffusion-weighted echo-planar MR image at b factor of 1000 s/mm2, the metastatic node exhibits a central hypointense area (arrow) corresponding to the partially necrotic portion of the node. The mean apparent diffusion coefficient of the node was 0.410 × 10−3 mm2/s.
