Materials and Methods: In this study 100 referred patients with different confirmed cancers were evaluated after intravenous injection of 99mTc-MDP and performance of Ant & Post whole body bone scan with gamma camera. Results: The scans showed no significant statistical correlation between the signs of diseases and the findings of bone scan(p>0.05), metastatic lesions are multiple and in more than 66% of cases the axial skeleton was involved.The prevalence of skeletal metastases from most common cancers including lung,breast and prostate correlates relatively with other reports. Conclusion: Performing whole body bone scan in addition to the recognition of management protocol prevents from excess actions resulting in worsening of disease.At the present time,scanning with 99mTc-MDP is the most sensitive and economic method in the diagnosis of metastatic regions.
