FDG-PET-CT scan images pre-and post-chemotherapy. A Pre-treatment axial section of FDG-PET-CT at mid-thoracic level showing metabolically active necrotic mediastinal lymph nodes and parenchymal lesions in the lungs. B Pre-treatment coronal section demonstrating metabolically active necrotic mediastinal and lung lesions. C Post-treatment axial images of FDG-PET-CT at mid-thoracic level showing complete resolution of the previously noted lung lesions with no significant residual activity. Background uptake seen on these images is due to physiological brown fat activity. D Post-treatment coronal section of FDG-PET-CT with no residual metabolically active disease. Supraclavicular fossa shows marked background of physiological brown fat activity
