Normal Variants and Pitfalls of 18F_FDG PET/CT Imaging in Pediatric Oncology
Обзор
Detection Normal variants and pitfalls of 18\_F \_FDG PET/CT imaging in pediatic oncology.
Подробное описание
Although pediatric cancer is relatively rare compared with adult cancer, it is the second most common cause of death, after injury in children and adolescents. lymphoma, Leukemia, and brain cancer, account for more than half of pediatric cancers, followed by neuroblastoma, soft-tissue sarcomas, Wilms tumors, and bone tumors .
18Fluorine-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) plays an important role, staging, restaging, response to treatment in childhood malignancies. PET-only examinations have been replaced by hybrid systems in the recent decades, where PET and CT are used together in oncology. In this imaging system, PET and CT are used together for functional data and morphological information, respectively. (2) Although 18F-FDG PET/CT is now well established as an accurate method for the staging and restaging of various cancers, it is also well recognized that many false-positive results can occur .
The normal distribution of FDG uptake in children differs from adults. Also, even though FDG is used widely in oncology, it is not tumor specific. Uptake of FDG may be seen in numerous benign conditions, including inflammation, infection, and trauma. Proper interpretation of pediatric FDG PET/CT studies requires knowledge of the normal distribution of FDG uptake in children, and an insight into the physiologic variants, benign lesions, and PET/CT related artifacts.
By understanding the potential causes of misinterpretation, we can increase the accuracy of interpretation, decrease the number of unnecessary follow-up studies and improve treatment outcome.
Вмешательства
- Диагностический тест PET/CT
is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity. A PET scan can often detect the atypical metabolism of the tracer in diseases before the disease shows up on other imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI).
