Experience of ^87mSr Bone Scintigraphy by Mini-Scanning Method

Abstract

^87mSrbone scintigraphy was performed in 22 cases of bone metastasis or suspected bone metastasis of malignant tumors and 1 case of necrosis of the head of the femur. This mini-scanning method showed abnormalities in 4 out of 6 cases in which bone metastasis was demonstrated by roentgenography. No abnormalities were observed in 15 out of 16 cases in which no abnormalities were seen by roentgenography. Abnormalities were observed in the lesion in one case of necrosis of the head of the femur as indicated by roentgenography. The mini-scanning method with^87mSrfailed to demonstrate any abnormalities in 3 out of 23 cases. Causes for these failures were examined, discussing problems of the mini-scaning method and of the use of^87mSras radioisotope for scintigraphy.
