Nuances of PET Interpretation in Thoracic Oncology: More Than Just Lung Cancer

摘要: 18F-FDG PET/CT scans portray living biology and are indispensable in thoracic oncologic evaluations, including presurgical staging of NSCLC, patient selection and target-volume definition in curativeintent radiation therapy (RT), and the evaluation of patients with suspected recurrence after definitive therapy. FDG-PET is also superior to CT for response assessment after definitive chemoradiation. 1 The indications for PET/CT will continually expand as thoracic oncology becomes more complex with new immunotherapies and tyrosine kinase inhibitors (TKIs) and with the increasing use of stereotactic ablative body radiotherapy (SABR). 2 Physicians interpreting PET must be aware of the clinical state of the patient beyond a simple request for “lung cancer imaging,” and they must fully understand the nuances regarding acquisition and interpretation of PET/CT scans.
