## Overview[edit | edit source]

Other imaging findings of non-small cell lung cancer include PET and pulmonary angiography.

## Other Imaging Findings[edit | edit source]

### PET[edit | edit source]

PET scanning with the tracer fluorine-18 (F-18) fluorodeoxyglucose (FDG), called FDG-PET, is widely used in the diagnosis of non-small cell lung cancer, for the following reasons:[1][2]

* General follow-up
* Characterization of treatment response
* Staging modality (in the risk of missing occult disease)

* Findings associated with non-small cell lung cancer on PET/CT include:
* 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.

### Pulmonary Angiography[edit | edit source]

* On pulmonary angiography, findings of non-small cell lung cancer, include:[3]
* Evaluation of central pulmonary artery invasion
