ABSTRACT
Figure 9.1 99mTcO 4 salivary gland study. (A) Anterior view of face and neck. (B) Left lateral view of face and neck. Normal salivary
gland image at 15 minutes after injection.
Figure 9.2 (A,B) 99mTcO 4 salivary gland study. Patient with history of
parotid gland swelling. (A) Dynamic images of face and neck following IV injection of 99mTcO
vary glands up to 14 minutes. A sialagogue given at 15 minutes releases tracer from the salivary glands into the mouth. (B) Areas of interest over the parotid and submandibular glands and the time/activity (T/A) curves from the submandibular and parotid glands. There is uptake of 99mTcO
erally. At 15 minutes, following salivary gland stimulation (lemon juice), there is good symmetrical emptying of radio activity from all four glands. Functioning parotid and submandibular glands with no evidence of obstruction.
