Overveiw
A bone scan may demonstrate bone metastases. FDG(18 F fluoro deoxyglucose) PET scans along with contrast enhanced CT may be helpful in the diagnosis of extent of Pancoast tumor.
Other Imaging Findings
Bone Scintigraphy
A bone scan may demonstrate bone metastases.
PET scan
- FDG (18 F fluoro deoxyglucose) PET scans along with contrast enhanced CT may be helpful in the diagnosis of extent of Pancoast tumor. Findings on FDGPET/CT suggestive of Pancoast tumor include:[1]
- Benefits of FDGPET/CT include:[2]
- Accurate delineation of the viable tumor from surrounding atelectasis and collapse or consolidation.
- It may further lead to a change in staging and treatment options of the lung cancer.
- Provide guidance for the biopsy.[3]
