    Computed tomography allows assessing the character of bone tumors. Although not as accurate as magnetic resonance imaging in the determination of the extent of soft tissue and bone marrow involvement, computed tomography is superior in the evaluation of cortical erosion, fracture, and internal characteristics such as ossification or calcification, also reveals associated soft-tissue masses and important adjacent anatomical structures, especially in the pelvis and spine.

    Computed tomography of the lungs is an essential part of staging for a patient who has a malignant musculoskeletal tumour. The lung is the most common site of metastatic disease in these patients, and computed tomography is a more sensitive method for the detection of metastatic disease than is conventional radiography of the chest.

    And lastly CT guided biopsy can be used in tumors with soft tissue component or soft tissue extension with accuracy about 96%.
