Abnormal focal tracer uptake in the jaw during conventional bone scintigraphy is a quite frequent finding usually not related to malignant disease. In patients undergoing radionuclide therapy with lanthanoids or rhenium, the appearance is also quite frequent. It�?¼s origin so far has not been studied in a large number of patients. Objective, to evaluate the underlying reason of abnormal focal tracer uptake in the jaw in patients who underwent 153Sm-EDTMP therapy for painful metastatic lesions. Methods, out of 138 patients, 82 revealed a positive result, 60 males and 22 females (mean age: 63.9 � 13.9years; range 19-90 years), with metastatic bone pain were examined. Their lesions were judged by a dentist clinically and radiologically. Results, the most frequent reason of increased focal uptake in the group of mainly prostate and breast cancer patients was inflammation in 13 (24.5%) and 9.. View More»
