The value of PET-CT to staging. Patient with non-small cell lung carcinoma. The tumour in the right upper lobe shows avid tracer uptake (SUVmax =19.4). There is a 5 mm station 4R node adjacent to the azygos vein and superior vena cava on the staging CT scan. This shows tracer uptake on the PET-CT (SUVmax =9.7) and was shown to contain tumour cells on endo-bronchial ultrasound guided sampling. If PET-CT had not been performed this N2 node would have been missed. PET-CT, positron emission tomography-computed tomography.
