High 18F-Fluorodeoxyglucose Uptake in Adrenal Angiomyolipoma
Adrenal angiomyolipoma is an extremely rare tumor, although computed tomography (CT) or magnetic resonance imaging findings of adrenal angiomyolipoma have been reported, there are no reports regarding integrated fluorine-18-fluorodeoxyglucose positron emission tomography and computed tomography ((18)F-FDG PET/CT) imaging. We report a case of adrenal angiomyolipoma showing a significantly high u...
متن کاملHigh 18F-fluorodeoxyglucose uptake in cardiac tumor
BACKGROUND Cardiac tumors, especially malignant, are rare but aggressive tumors that mostly arise from the mesenchymal cells and represent a challenging diagnosis for clinicians. Recently, fluorine-18-fluorodiography positron emission tomography and computed tomography (F-FDG PET/CT) is an increasingly popular new technique with diagnosis of tumor. METHODS We report a case of a right heart tu...
متن کاملAdministration of unfractionated heparin with prolonged fasting could reduce physiological 18F-fluorodeoxyglucose uptake in the heart.
BACKGROUND The physiological uptake of 18F-fluorodeoxyglucose (FDG) in the heart often interferes with the accurate diagnosis of inflammatory cardiac diseases (CDs). Unfractionated heparin (UFH) administration may suppress its uptake through the alteration of myocardial metabolism. PURPOSE To clarify the effectiveness of UFH administration to suppress the physiological FDG uptake in the heart...
متن کامل18F-Fluorodeoxyglucose Uptake and Tumor Hypoxia: Revisit 18F-Fluorodeoxyglucose in Oncology Application
UNLABELLED This study revisited (18)F-fluorodeoxyglucose ((18)F-FDG) uptake and its relationship to hypoxia in various tumor models. METHODS We generated peritoneal carcinomatosis and subcutaneous xenografts of colorectal cancer HT29, breast cancer MDA-MB-231, and non-small cell lung cancer A549 cell lines in nude mice. The partial oxygen pressure (pO2) of ascites fluid was measured. (18)F-FD...
متن کاملDiagnostic value of 18F-fluorodeoxyglucose uptake parameters to differentiate rheumatoid arthritis from other types of arthritis
We aimed evaluate F-fluorodeoxyglucose uptake at major joints for differentiating patients with rheumatoid arthritis (RA) from those with non-RA arthritis using F-fluorodeoxyglucose (FDG)-positron emission tomography (PET).Eighteen patients with RA (13 women; age, 66.8 ± 13.2 years) and 17 patients with non-RA (6 women; age, 50.8 ± 12.5 years) were included. Twelve joints of each patient were e...
