The most important determinators in the analysis of a potential bone tumor are: 1. Most primary bone tumors are seen in patients < 30 years. But other imaging tests might be needed as well. 2. Bone scan is currently used to determine the presence of metastatic and polystotic bone disease and the involvement of a bone by an adjacent soft- tissue sarcoma. Bone cancer can weaken the bone, but most often the bones do not fracture (break). Radiographs are recommended as the initial imaging modality for the evaluation of bone pain [1, 2], and standard radiographic techniques are typically adequate for tumor imaging.The long bones should be imaged with frontal and lateral views, whereas joint imaging benefits from the addition of oblique views. In the realm of bone tumor imaging, scintigraphy is used to confirm that a lesion is solitary when first identified on a radiograph and is most consistently performed to determine the distribution of metastasis when this is a consideration based on the initial lesion. The majority of tumors in the pelvis are malignant (metastases, myeloma, chondrosarcoma, Ewing-, osteo-, and MFH/fibrosarcoma), while those in the proximal femur are in majority benign (fibrous dysplasia, solitary bone cyst, and osteoid osteoma).
