Positron emission tomography (PET) is a unique imaging technique that provide* details of functional processes in the body. PET has many applications but is most widely used in thoracic oncology because of its superiority over other imaging techniques in staging nodal and metastatic disease [1]. However, the poor anatomic detail of PET can lead to errors in diagnosis and staging. Through the integration of CT and PET, form and function are merged to create a better imaging tool, particularly in the staging of non-small cell lung cancer (NSCLC).
