Prostate cancer (PCa) is one of the few neoplasms that are not well served by 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). As a result, a number of PET tracers have been developed to target particular biological features of PCa. Such agents can be used for diagnosis, staging, identification of biochemical recurrence (BCR) and evaluation of metastatic disease. Here, we focus ...

BACKGROUND AND AIMS Retrospectively analyze the sensitivity of 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) in the diagnosis of gastric malignancy compared with gastric endoscopy in persons with nonspecific symptoms and evaluate the necessity of 18F-FDG PET-CT scan before surgery. MATERIALS AND METHODS A total of 53 patients with gastric malignancy ...

A 53-year-old man with a history of nausea and elevated liver functions presented to our clinic. A CT scan showed a small tumor in the right lobe of the liver. Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography confirm abnormal metabolic activity with a high standardized uptake value of 7.3 in the lesion. These findings could indicate a malignancy such as well-differentiated ...

18F-FDG PET/CT is a well-established method used both for staging and follow-up examinations of patients with lymphoma. In addition, it provides valuable information considering bone marrow infiltration.1 We present a case of 46-year-old female with lymphocyte-depleted Hodgkin’s lymphoma who underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) for initi...

Measurement of intratumoral heterogeneity by 18F-fluorodeoxyglucose (18F-FDG) Positron Emission Tomography (PET) is a valuable modality, which showed correlation to response of treatment and prognosis in various malignancies. PET-based texture analysis for tumor heterogeneity is a potential predictive factor for cervical cancer and related to lymph node metastasis, tumor volume, response of tre...

A 67-year-old male presented with a metastatic carcinoma in the right side of the neck from an unknown primary site. 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography showed increased 18F-FDG uptake in the right larynx and right neck lymph nodes. A smooth lesion was identified in the submucosa of the right supraglottic region via a suspension laryngoscopy under gener...

18F-fluorodeoxyglucose positron emission tomography (FDG-PET) has been widely incorporated in cancer management. Although, it has increased sensitivity, 18F-FDG is not tissue specific thus posing diagnostic dilemma in certain situations. False positivity in pulmonary nodules have been seen in various inflammatory, infective as well as post operative conditions while false negativity is common w...

Positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) is used in staging, restaging, and evaluation of therapy response in many cancers as well as differentiated thyroid carcinomas especially in non-iodine avid variants. Its potential in less frequent thyroid tumors like medullary, anaplastic thyroid cancers, thyroid lymphoma and metastatic tumors of the th...
