Longitudinal monitoring of tumor growth by MRI and 18F-FDG-PET. Upper panel A Graph displaying weekly tumor volumes (mean, standard deviation) from T2-weighted MRI (vMRI) and metabolic tumor volume (MTV) from 18F-FDG-PET imaging in non-treated mice. The graph is based on imaging of 12 mice in Week 3 (14 mice for MRI), 10 mice in Week 4 and four mice (eight mice for MRI) in Week 5. B (T2-MRI) and C (18F-FDG-PET-CT maximum intensity images, MIP) display the growth of a tumor (arrows) imaged weekly by MRI and PET in a single, representative mouse. b bladder, k kidney, 18F-FDG fluorodeoxyglucose, MTV metabolic tumor volume, SUV standardized uptake value, vMRI tumor volume from MRI
