This learning module describes different imaging studies for bone tumors of the foot.
This learning module describes different radiographs and in what situations to use which type and why.
For bone and soft tissue lesions alike, two orthogonal high-quality plane radiographs are the best initial imaging study. Based on the characteristics of the tumor, its location, and the findings from the history and physical examination, additional cross-sectional imaging is often necessary.
Both fine cut CT scans and high field strength MRI scans are essential to understanding the local extent, anatomic relationships, and possible origins of bone tumors.
When a bone lesion in the foot or ankle area is suspected to be a metastasis from an unknown primary site, a CT scan of the chest, abdomen, and pelvis with oral and intravenous contrast is recommended as the next step in management.
Bone scans are useful in identifying multiple and occult bone lesions in patients with metastasis. For patients with solitary bone tumors where metastasis is not suspected, and in soft tissue tumors, bone scan findings are nonspecific.
