Overview
Other diagnostic studies include bone scintigraphy, PET scan, and molecular tests.
Lung Cancer Other Diagnostic Studies
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 lung cancer. Findings on FDGPET/CT suggestive of lung cancer include:[1]
- Solitary pulmonary nodule
- 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 of the lung cancer.
- Provide guidance for the biopsy.[3]
Molecular Test
Molecular tests include epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) mutation. Specific targeted agents may be administered to patients if these mutations are present.
