FIG. 1.

Illustration demonstrating ultrasound scanning of the parotid gland (drawn by Eric Jablonowski, Department of Radiology and Imaging Science, Emory University, Atlanta, GA).

FIG. 2.

Ultrasound B-mode images of normal (a) and post-RT (b) parotid glands and their GLCM in four directions (0°, 45°, 90°, and 135°). (a) Ultrasound image of the left parotid gland of a 41-yr-old healthy volunteer, revealing homogeneous echotexture and fine soft tissue echogenicity. (b) Ultrasound images of the left parotid gland of a 52-yr-old laryngeal cancer patient, 22 months post-RT, revealing heterogeneous echotexture.

Image of FIG. 3.
FIG. 3.

Textural features (Mean ± STD) of the normal and post-RT parotid glands (N g = 16, d = 4, θ = 90°).
