Overview
Other imaging findings of squamous cell carcinoma of the lung, include: PET/CT, and pulmonary angiography.
Other Imaging Findings
PET/CT
- PET scanning with the tracer fluorine-18 (F-18) fluorodeoxyglucose (FDG), called FDG-PET, is widely used in the diagnosis of squamous cell carcinoma of the lung, for the following reasons:[1][2]
- General follow-up
- Characterization of treatment response
- Staging modality (in the risk of missing occult disease)
- On PET/CT, findings of squamous cell carcinoma of the lung, include:[2]
- The CT scan demonstrates abnormalities such as a lung nodule or enlarged lymph nodes. Whereas, the PET scan reveals increased metabolism in structures which contain rapidly growing cancer cells
- Intense radiolabeling of tissues with high glucose uptake, such as the brain, the liver, and malignant tumor cells.
- On gallium-67-scan, characteristic findings of non-small cell lung cancer, include:[2]
- Gallium uptake is mainly dependent on tumor size (limited practical value)
Pulmonary Angiography
- On pulmonary angiography, findings of squamous cell carcinoma of the lung, include:[3]
- Evaluation of central pulmonary artery invasion
