Overview

Other imaging studies include PET/CT scanning, which may be useful as a staging modality, detection of occult disease, and malignancy assessment.

Other Imaging Findings

PET/CT

• Other imaging studies include PET/CT scanning, which may be useful as a staging modality, detection of occult disease, and malignancy assessment.
• On PET/CT, findings of pulmonary nodule, may include:

• FDG uptake

• Likely malignant

• No FDG uptake

• Likely benign

False negative results for pulmonary nodule characterization, include:

• Small lesion size
• Low tumor metabolic activity
• Hyperglycemia
