Figure 1

Duplex sonograms of the salivary glands under different stimulation types. The sonograms of a healthy person (male, 47 years) show relative changes in blood perfusion of the submandibular gland induced by chewing-gum stimulation (a), non-stimulation (b), and lemon-juice stimulation (c). Blood flow information is superimposed in colour onto the conventional anatomical gray-scale image. The thick white lines within the thin white rectangles indicate the approximate glandular boundaries. The chewing-gum stimulation, non-stimulation, and lemon-juice stimulation are designated by CS, NS, and LS, respectively.
