This is an x-ray of the same thighbone as the one in the MRI images above. This x-ray was taken 14 years after surgical removal of Ewing's sarcoma and reconstruction using a bone graft with an artificial joint replacement.

X-ray: When a patient experiences pain that is suspected to be a result of bone cancer, the first step in diagnosis is usually to X-ray the area near the pain. When enough of the healthy bone in any area is worn away by metastatic lesions, the damaged area will show up as a dark spot on the X-ray that look like holes in the bones. Bone cancer in the femur. Lateral X-ray of a cancerous growth (cloudy area) at the lower end of one of the femurs of a 60-year-old patient. This is an osteochondrosarcoma, a type of cancer of bone and connective tissue. The patella (part of the knee joint) is at lower left. In many tumors, FDG-PET is more sensitive than a bone scan in diagnosing metastasis and assessing tumor response after therapy; however, the availability and cost of FDG-PET are also limiting factors. Despite lower sensitivity, bone scans are still valuable in detecting thyroid bone metastases and cannot be completely replaced by FDG PET . 4.2.
