AIM The aim was to compare the imaging findings of (18)F-fluorodeoxyglucose ((18)F-FDG) PET and integrated PET/CT in patients with primary, recurrent or metastatic ovarian cancer. MATERIALS AND METHODS 21 women with ovarian cancer were evaluated. All patients had a integrated PET/CT scan. Localization, infiltration and uptake intensity of [(18)F]FDG were evaluated on PET and PET/CT. The certa...

Objective(s): The present study aimed to evaluate the role of pretherapeutic 18fluorine-fluorodeoxyglucose positron emission tomographycomputed tomography (18F-FDG PET-CT) and maximum standardized uptake value (SUVmax) in guiding the treatment strategy and predicting the prognosis of esophageal carcinoma, using the survival data of thepatients.Methods: The present retrospective, cohort study wa...

objective: resistance of metastatic lymph nodes (lns) to high dose i-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. we evaluated the role of f-18 fdg pet/ct in the prediction of resistance to high dose i-131 therapy in patients with papillary thyroid cancer. methods: the subjects were 307 patients who underwent total or near total thyroidectomy fol...

PURPOSE In patients with peritoneal carcinomatosis (PC), cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is an evolving therapeutic approach with curative intention. The differentiation between posttherapeutic findings after HIPEC and relapse of PC is challenging. We evaluated the diagnostic value of F-18-FDG-PET/CT in patients with relapse of PC after HIPE...

UNLABELLED The timely detection of metastatic infectious foci in gram-positive bacteremia is crucial, because these foci often require prolonged antibiotic treatment or drainage. The diagnosis of metastatic infectious foci is difficult because localizing symptoms are often absent. We investigated whether (18)F-FDG PET/CT was able to detect such foci and whether detection influenced clinical out...

Primary meningeal melanomatosis is a rare, aggressive variant of primary malignant melanoma of the central nervous system, which arises from melanocytes within the leptomeninges and carries a poor prognosis. We report a case of primary meningeal melanomatosis in a 17-year-old man, which was diagnosed with (18)F-fluorodeoxyglucose (F-18 FDG) PET/CT, and post hoc F-18 FDG PET/MRI fusion images. W...

objective(s): the present study aimed to evaluate the role of pretherapeutic 18fluorine-fluorodeoxyglucose positron emission tomographycomputed tomography (18f-fdg pet-ct) and maximum standardized uptake value (suvmax) in guiding the treatment strategy and predicting the prognosis of esophageal carcinoma, using the survival data of thepatients.methods: the present retrospective, cohort study wa...

(18)F-FDG PET/CT is a valuable noninvasive tool in oncologic imaging, and its application in the diagnosis of liver metastases has been very convincing. Both the sensitivity and the specificity of (18)F-FDG PET/CT are high for detecting liver metastases from various tumors including colorectal, breast, and lung. Such liver metastases are typically (18)F-FDG-avid. We present atypical (18)F-FDG P...

BACKGROUND The aim of the study was to meta-analyze published data about prevalence and malignancy risk of focal colorectal incidentalomas (FCIs) detected by Fluorine-18-Fluorodeoxyglucose positron emission tomography or positron emission tomography/computed tomography ((18)F-FDG-PET or PET/CT). METHODS A comprehensive computer literature search of studies published through July 31(st) 2012 r...

UNLABELLED In newly diagnosed diffuse large B-cell lymphoma (DLBCL), the sensitivity of bone marrow biopsy (BMB) for the detection of bone marrow involvement (BMI) can be low because of sampling error if the BMI is focal and not diffuse. Although (18)F-FDG PET/CT is now recommended for initial staging of DLBCL, its role regarding BMI is not well defined. This study evaluated whether (18)F-FDG P...
