Figure 2 Ultrasonographic images of the submandibular glands obtained 18 hours after contrast administration. (A, B) Gray-scale images of the right (A) and left (B) submandibular glands demonstrate mild heterogeneous parenchymal echotexture with mild intraglandular ductal dilatation. (C, D) Color Doppler images demonstrate increased parenchymal vascularity within the right (C) and left (D) submandibular glands.
