Fig. 4From: Evaluation of metabolic response with 18F-FDG PET-CT in patients with advanced or recurrent thymic epithelial tumorsRepresentative images of baseline a and post-treatment b 18F-FDG PET-CT scan in a patient with thymic carcinoma. Fusion images of co-registered transaxial 18F-FDG PET and CT sections are shown. In the baseline scan SUVmax was 8.80 whereas the post-treatment study showed a SUVmax of 14.40. A 64% increase of 18F-FDG uptake was found in this patient with stable disease based on RECIST. The same maximum threshold of SUV was applied to PET images from pre-treatment and post-treatment scans as shown by the color scale on the leftBack to article page
