Tcを用いたに代表される唾液腺シンチは主に耳下腺，顎下腺に集積し，唾液として排泄される．クエン酸負荷による分泌刺激とあわせて唾液腺機能の指標となり，び漫性疾患では唾液腺炎，舌咽神経麻痺，放射線照射等の疾患で用いられる．腫瘍性病変においてもワルチン腫瘍とその他の鑑別に有効である．またFDG-PETはFDG集積の目安としての半定量値であるSUVを用いることで，唾液腺腫瘍の局所病変診断，病期診断，治療評価のいずれにおいても重要になり，今日の核医学画像診断には欠かせない存在である．

Salivary scintigraphy which is representative of those that uses Tc, gathers mainly at the parotid gland and submandibular gland and is excreted. It becomes the indicator of salivary gland function that matches the secretion stimulus through citric acid loading, and among mild chronic diseases, it is used in sialadenitis, glossopharyngeal nerve paralysis, and other radiation diseases. Even in neoplastic pathological changes, it is effective in the differentiation of Walthin's with other tumors. Also, FDG-PET, by using SUV which is a semiquantitative value as the approximation of FDG accumulation, becomes essential even in the examination of local pathological changes, disease stage, treatment and cure evaluation of salivary gland tumors, and must be present in today's nuclear medicine image examinations.

Salivary gland citin represented used TC is discharged as saliva after accumulating at salivary gland and submandibular gland. It becomes guidlines of salivary gland functioning together with secretion stimulus, and for Bi chronic disease, it is used for diseases such as salivary glanditis, glossopharyngeal paralysis and irradiation. Also for neoplastic lesion, it is effective to indicate vaccine tumor and others. Also as FDG-PET is used USV which is decision amount value for indication of FDG accumulation, it is important for both local lesion diagnosis of salivary gland tumor, staging and treatment evaluation, and it is inevitable for today's nuclear medicine imaging diagnosis.

Representing scintigraphy of salivary gland which is known for using Tc, Tc mainly accumulates in parotid gland and excrete as saliva. This will be an indication of the function of salivary gland together with the secretion stimulation by citrate loading and it will be used for the diffuse disease such as salivary glanditis, glossopharyngeal paralysis, irradiation. It is also effective for distinguishing benign tumor legion with Warutin tumor and others. Moreover, FDG-PET is indispensable for the diagnosis by nuclear medical imaging today in either of partial legion diagnosis, stage diagnosis, treatment evaluation of malignant tumor of salivary gland using SUV which is semi-quantitative value as the standard of FDG accumulation.
