Bone scanning was performed on 102 patients with malignancy. Positive results were obtained in 59.8% of the patients among which the metastatic rates for sternum
vertebrae
pelvis and extremity bones were 27.9%
21.3%
37.7% and 31.1% respectively. A compar tive study of 76 patients revealed that the positive rates obtained with bone scanning was higher than common X-ray examination (80.3% and 68.4% respectively). Thus
bone Scanning is a sensitive method for detecting bone metastases.
