5 Case of Bone Scan with 85Sr

Bone scanning was attempted in the five representative cases in various diseases such as primary bone tumor, inflammatory or traumatic changes, secondary metastatic bone tumor and changes in the hematopoietic system with 85Sr which is available at this time. Each findings were correlated to the X-ray findings. Scan findings were more appreciable than the X-ray findings in elucidation of extent of bone pathology in cases of primary bone tumor and fracture cases. Especially, increased radioactivity was noted on the clinically suspected region which were not demonstrated on the plain X-rays.
