do pet scans show lung cancer?

Adjunctive: Pet scans utilize a special sugar molecule or glucose, and attaches a harmless piece of radioactivity to it (fdg). The FDG is taken up by metabolically active tissue, and glows on imaging. Often tumors or lung cancers are metabolically active. A pet scan can be fused with a ct scan, and if a suspicious lung mass on ct scan is metabolically active by pet, it may indicate it is a lung cancer.

Sort of...: The pet scan non-specifically show very metabolically active (consuming lots of energy), and lung cancer and its metastasis fit that category. It is not specific. Benign conditions like sarcoid can also make pet studies glow very brightly as well. Slow growing lung cancer, broncheoalveolar may not be pt avid.

Not exactly: They show lesions that are suspicious for cancer (including lung cancer). Typically co fir action with a biopsy is required before treatment is initiated.
