Abstract
The authors used 99mTc for scintigram in diagnosis of two cases with chronic inflammatory lesions of the salivary gland.
Case 1 was a 28-year-old male with chronic inflammation of the left submandibular gland while case 2 was a 69-year-old male with the same disease.
Impaired functions of the salivary glands were shown as a scarcity in intake of 99mTc- Pertechnetate by the salivary glands. Pathological examinations of the salivary glands showed advanced fibrosis in both of the cases.
99mTc has various advantages in use with scintigram for diagnosis of salivary gland diseases, which may be favorably compared to sialography which causes invariably pain on the side of the patients.
Some of the other advantages are that the 99mTc has a short half-life of 6.1 hours, emits only the γ-rays with its energy being 0.14 Mev, and has a good scan-effect.
