摘要: PURPOSE: To retrospectively compare fluorine 18 fluorodeoxyglucose (FDG) positron emission tomographic (PET) and computed (CT) findings at the same anatomic locations in patients with lymphoma by using a combined PET/CT scanner to analyze lesions on metabolic bases evaluate causes of discrepant between two modalities. MATERIALS AND METHODS: The institutional review board allowed an exempt retrospective cancer PET database, informed consent was waived. study HIPAA compliant. Fifty-three (20 Hodgkin 33 non-Hodgkin; mean age, 43 years; range, 12–83 years) who underwent FDG were included. CT images interpreted nuclear medicine physicians one radiologist, respectively, blinded other imaging findings. Concordant regarded as positive or negative for lymphoma. site discordant defined disease if it accompanied ...
