case_images: Gray scale ultrasonography of the submandibular gland (right side). The gland is enlarged (total volume around 12 cmc) with well-defined delineation, inhomogeneous structure, hypoechoic area in the center (belongs to the hilum of the gland), and hyperechoic areas under the capsule (belong to the parenchyma).

case_images: Figure 2 represents a combination between 2D ultrasonography and "colour flow map" (CFM, or "duplex sonography"). From the first viewing, we can easily detect, by its enlargement, the gland swelling (Figure 1) and the hyper vascular pattern (Figure 2), both of these pieces of information being highly suggestive for the inflammation diagnosis.
case_images: Colour coded Doppler ultrasonography (same case as Figure 1). In the central part of the gland there are vessels (blue and red according to the direction of the blood flow in relation to the transducer). The amplitude and extension of the colour signal are suggestive of hyperaemia (in this case it was an acute inflammation of the submandibular salivary gland).

case_images: Elastogram of the submandibular gland (on the right side, inflamed gland) using the ARFI procedure. The measurements are made in an area of glandular parenchyma, in a predefined rectangular area, vessel free. The ultrasound speed is 2,55 m/sec.

case_images: Figures 3 and 5 (obtained on the right salivary swollen gland) and Figures 4 and 6 (obtained on the left side, normal gland) represent elastography in quantitative mode (Figures 3 and 4), color mode (Figures 5 and 6) (ARFI tissue imaging mapping color). 
case_images: Elastogram of the submandibular gland (left side, normal gland) by means of ARFI procedure. The sample rectangle is positioned subscapular, in a similar position as it was on the right side gland. The ultrasound speed in the measured area is 1,36 m/sec.

case_images: Qualitative (black and white coded; black is rigid; white is soft) elastogram (ARFI procedure) of the submandibular inflamed gland (right side). The pathological area inside the gland is well defined. This area presents a high rigidity index in relation to the amplitude of the pathological process.

case_images: Qualitative (black and white coded; black is rigid; white is soft) elastogram (ARFI procedure) of the normal gland (considered to be the "witness," on the left side). The dispersion of the vectors of speed is obvious. There is no obvious compact hard parenchyma as in the right pathological gland (Figure 5).
