18F-FDG PET is emerging as a useful tool in the staging and restaging of many malignant neoplasms, such as lymphoma, lung cancer, colorectal cancer, head and neck cancer, breast cancer, and melanoma. To accurately interpret 18F-FDG findings one must be familiar with the normal physiologic distribution of the tracer, frequently encountered physiologic variants, and benign pathologic causes of 18...

The purpose of this study was to systemically review the available literature regarding the diagnostic performance of positron emission tomography (PET) using 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) in patients with thymic epithelial tumors. We reviewed 13 studies that evaluated the diagnostic role of thymic epithelial tumors with [18F]FDG-PET. [18F]FDG-PET is a useful radiological modality ...

Metastatic infection is an important complication of Staphylococcus aureus bacteremia (SAB). Early diagnosis of metastatic infection is crucial, because specific treatment is required. However, metastatic infection can be asymptomatic and difficult to detect. In this study, we investigated the role of 18F-FDG PET/CT in patients with SAB for detection of metastatic infection and its consequences...

UNLABELLED A widespread application of integrin αvβ3 imaging has been emerging in both pre-clinical and clinical studies. But few studies reported its value as compared with 18F-FDG PET, especially for differentiated thyroid cancer (DTC). In this study, we compared the tracer uptake of 18F-AIF-NOTA-PRGD2 and 18F-FDG in lymph node metastasis of DTC to evaluate 18F-AIF-NOTA-PRGD2 as compared with...

UNLABELLED Accurate evaluation of primary tumors and cervical lymph node status of squamous cell carcinoma (SCC) of the oral cavity is important to treatment planning and prognosis prediction. In this prospective study, we evaluated the use of 18F-FDG PET, CT/MRI, and their visual correlation for the identification of primary tumors and cervical nodal metastases of SCC of the oral cavity with h...

the use of [18f]-2-fdg has been increasing in recent years. this agent was originally used for evaluation of cns glucose uptake and pathologic conditions by positron emission tomography (pet). in view of increasing demand for this agent, its production has been started at cyclotron dept., nuclear research center for agriculture & medicine-karaj iran (nrcam). in this paper, [18f]-fdg synthes...

Correct staging is the most crucial for the treatment outcome in cancer management. Molecular imaging with 18F-fluoroestradiol (FES) positron emission tomography-computed tomography (PET-CT) targets estrogen receptor (ER) and may have a higher incremental value in diagnosis by aiding specificity. We enrolled 12 female breast cancer patients prospectively and did 18F-FES PET-CT and 18F-fluorodeo...

TO THE EDITOR: We read with great interest the recent article by Cheung et al. on the utility of 11C-acetate/18F-FDG PET/CT for clinical staging and appropriate selection of patients with hepatocellular carcinoma (HCC) for liver transplantation based on the Milan criteria (1). The authors of this study were able to show the strength of PET/CT over dynamic contrast-enhanced CT to detect HCCs (pa...

18F-Fluorodeoxyglucose positron emission tomo-graphy and computed tomography (18F-FDG PET/CT) has limited value in well-differentiated neuroendocrine tumors. The value of 18F-FDG PET/CT in non-functioning pancreatic neuroendocrine tumors, which are often poorly differentiated, malignant, and present at an advanced stage, was also thought to be limited. This study was performed to evaluate the c...
