Submandibular gland function following transoral sialolithectomy was examined by 99mTc-pertechnetate sialo-scintigraphy in 10 cases. An intraindividual comparison between the function of the treated gland and that of the contralateral normal gland was made using a time-activity curve. Although glandular recovery was not affected by the duration of symptoms or the existence of the symptom at mealtimes, it was inversely proportional to the size of the calculus. Furthermore, the prognosis was more favorable in patients when the anatomically normal orifice of the submandibular duct was preserved.

Angiodysplasia of the right colon may be difficult to diagnose. The usual methods of choice, selective abdominal angiography and colonoscopy, may be impracticable or fail. When bleeding occurs, 99mtechnetium blood-pool scintigraphy is a simple and reliable method of localizing vessel leakage. We present a case of an 84-year-old woman with severely bleeding angiodysplasia, where the source of bleeding was localized by means of scintigraphy using 99mTc in vivo labeled red blood cells. After right hemicolectomy, the angiodysplastic lesion was confirmed by specimen venography utilizing a barium gelatin mixture.
