Sir,The recent report on F-18fluorodeoxyglucose (F-18-FDG) positron emission tomography (PET)/computed tomography (CT) in the detection of recurrence carcinoma cervix is very interesting.[1] Bhoil et al. concluded that “PET/CT appears to have an important role in detecting recurrence following primary treatment of cervical cancer.”[1] It is no doubt that the tool can be useful in investigative medicine for searching malignancy. However, there are some concerns on the F-18-FDG PET/CT. Errors can be seen in some cases. The good examples are the errors that can be seen in the case with existed atherosclerotic plaques[2] and lymphadenopathy due to infectious etiologies.[3] To diagnose, the careful interpretation on investigation result accompanied with available history and clinical features of the patients is required.
