Sequential dynamic PET and dynamic MR imaging in N-staging of lung cancer patients

Purpose: For therapy stratifications, staging of lung cancer is typically performed with FDG-PET/CT. In the context of new established integrated PET/MR-scanners, the combination of well established dynamic contrast enhanced (DCE) MRI imaging with dynamic PET might be an upcoming imaging modality. In order to evaluate potential perfusion changes between benign and malignant lymph nodes in lung cancer patients, DCE MRI was correlated to microcirculatory and sub cellular dynamic parameters in FDG-PET/CT. Materials and Methods: According to the clinical routine, a total number of 14 patients with lung cancer were e…
