Overview
Other diagnostic studies include bone scintigraphy, PET scan, and molecular tests.
Lung Cancer Other Diagnostic Studies
Bone Scintigraphy
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][2]
- Solitary pulmonary nodule
- Provide guidance for the biopsy
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.
