BACKGROUND: Fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has become a preferred imaging modality for the evaluation of solitary pulmonary nodule (SPN), particularly in the developed world. Since FDG can concentrate in infective/inflammatory lesions, the diagnostic utility of FDG-PET can be questioned, particularly in regions endemic for infectious decisions. AIM: To evaluate the accuracy of FDG-PET/CT in evaluation of SPNs in a population endemic for infectious disease and to assess if regional variations have an impact on its effectiveness...

INTRODUCTION: Whole body PET CT is an important investigation tool in malignancy patients and helps in ascertaining the metabolic activity and exact stage of the disease. However, like any other investigation, false positive results do exist and certain diseases other than cancer may show increased uptake. Hence, a careful evaluation of PET CT and clinical correlation in malignancy patients is a must to accomplish the suitable treatment. METHODS: In this retrospective observational study, seven cases of cancer with concomitant tuberculosis were included...

Positron emission tomography/computed tomography (PET/CT) using 2-deoxy-2-(fluorine-18) fluoro-D-glucose ((18)F-FDG) has become a standard diagnostic modality in oncological practice. F18-FDG PET/CT is sensitive in detecting malignancy; however, specificity is low in differentiating infections or inflammatory diseases from tumor. In the present case study, we report a patient with postoperative carcinoma of tongue presenting with cervical lymphadenopathy and fever. The PET/CT scan showed metabolically active generalized lymphadenopathy, and a possibility of lymphoma was suggested...
