Computed tomography of orthopedic neoplasms.
CT facilitates diagnosis of orthopedic neoplasms by recognition of both the internal contents of the lesion and its borders with surrounding soft tissues. Involvement of adjacent vital organs and spread within the medullary canal are important for planning resection or amputation. Changes in the size of the lesion may be seen on CT scans following radiation therapy, and metastatic lesions to bone and lungs may be detected with high sensitivity. Biopsy performed with CT guidance is both safe and effective.
