It is a valuable tool for staging and restaging of some tumors and has an important role in the detection of recurrence in asymptomatic patients with rising tumor 18f pet levels and patients with negative or equivocal findings on conventional imaging techniques.

Metrics details. Two reviewers independently selected studies according to the inclusion and exclusion criteria. A reviewer extracted relevant data and assessed the quality of the eligible studies. Subgroup analysis was performed. Peer Review reports. Malignant tumors are common public health problems worldwide and lead to tumor-related complications and death.

The use of this novel imaging modality in oncology has been rapidly evolving. However, due to its detection of cellular metabolism, it is not truly tumor specific. Imaging readers, particularly the nuclear physicians, therefore need to be aware of normal physiological variants of uptake, as well as potential pitfalls and artifacts when imaging with 18 F-FDG. This is true for musculoskeletal uptake, where more than often, infective and inflammatory processes should not be mistaken for malignancy. The impact of this article is to help in the minimizing of poor imaging quality, erroneous interpretations and diminishes misdiagnoses that may impact on the adequate management of patients with undesirable consequences. Due to its non-specific nature for malignant lesions, 18 F-FDG may also be used to detect processes involved in infection and inflammation. Therefore, issues related to pitfalls and normal variants should be kept in mind during imaging interpretation. This article will be focusing on imaging illustration pitfalls and normal variants related to musculoskeletal, infection, and inflammation with limited narrative related to the topic. FDG is a glucose analog and thus follows the similar fate as glucose in living tissues. Glucose enters the cell through glucose transporters, gets phosphorylated to glucose-6 phosphate by hexokinase, and further metabolism occurs 1. FDG, however, does not get metabolized further once it is phosphorylated to glucose-6 phosphate and is trapped inside the cell.

Finally, we analyzed the prognostic significance of age, tumor size, and stage for the external and validation cohorts separately, 18f pet by multivariate analyses with univariately derived prognostic imaging features to determine whether these imaging features added statistically significant independent information to prognosis in both cohorts. Clin Cancer Res, 18f pet.

Carbohydrate diversity is foundational in the molecular literacy that regulates cellular function and communication. Consequently, delineating and leveraging this structure—function interplay continues to be a core research objective in the development of candidates for biomedical diagnostics. A totemic example is the ubiquity of 2-deoxy[ 18 F]-fluoro- D -glucose 2-[ 18 F]-FDG as a radiotracer for positron emission tomography PET , in which metabolic trapping is harnessed. Building on this clinical success, more complex sugars with unique selectivities are gaining momentum in molecular recognition and personalised medicine: this reflects the opportunities that carbohydrate-specific targeting affords in a broader sense. In this Tutorial Review, key milestones in the development of 2-[ 18 F]-FDG and related glycan-based radiotracers for PET are described, with their diagnostic functions, to assist in navigating this rapidly expanding field of interdisciplinary research.

Fludeoxyglucose F18 is a radioactive tracer that acts as a glucose analog and is used for diagnostic purposes in conjunction with positron-emitting tomography PET to localize the tissues with altered glucose metabolism. It does not have therapeutic use.
