Factors influencing the pattern and intensity of myocardial 18F-FDG uptake in oncologic PET-CT imaging
Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...
متن کاملTumour response evaluation with fluorodeoxyglucose positron emission tomography: research technique or clinical tool?
The evaluation of treatment response is an established role for imaging in oncologic research and clinical practice. In early phase trials, imaging response criteria are used to determine the presence and magnitude of the drug effect on tumour to aid decisions concerning progress to late phase trials, and to inform dose selection and scheduling. In late phase trials and clinical practice, the i...
متن کاملDetection of extra-cardiac hypermetabolic foci by [18F]FDG PET/CT in case of infective endocarditis and post antibiotic therapy response assessment
The diagnosis of prosthetic valve endocarditis continues to present a diagnostic challenge, due to the lower sensitivity of the modified Duke criteria and a higher percentage of negative or inconclusive echocardiography results. Diagnostic delay might result in significant morbidity/mortality. Imaging modalities like 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/comput...
متن کاملComparison of FDG-18 Uptake and ADC Values in Thyroid Cancer
PET/MRI is a relatively recent diagnostic tool for the evaluation of oncologic disease. It combines the excellent soft tissue contrast of MRI with the physiologic data regarding glucose metabolism of PET. It has been described that ADC values may be useful in oncologic imaging, with development of central necrosis within a malignancy corresponding with increased ADC values. It has long been kno...
متن کاملPresent and future roles of FDG-PET/CT imaging in the management of gastrointestinal cancer: an update
Positron emission tomography/computed tomography (PET/CT) integrated with 2-[18F]fluoro-2-deoxy-D-glucose (FDG) is a useful tool for acquisition of both glucose metabolism and anatomic imaging data, as only a single device and one diagnostic session is required, thus opening a new field in clinical oncologic imaging. FDG-PET/CT has been successfully used for initial staging, restaging, assessme...
