18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is an evolving tool in the field of oncology. 18F-fluorodeoxyglucose, however, is not a specific tool for malignant tumor that it may also accumulate in benign processes. To avoid false-positive interpretation of 18F-FDG-PET/computed tomography (CT), having knowledge of the potential pitfalls is important.The authors present a ca...

The study is based upon 80 patients, suspected of having recurrent laryngeal cancer, who underwent an 18F-FDG PET study on a coincidence camera and a laryngoscopic biopsy under general anaesthesia. The potential value of 18F-FDG PET in the detection of local relapses of laryngeal cancer after radiotherapy by use of a coincidence camera was prospectively assessed, and a cost-effectiveness analys...

BACKGROUND In human immunodeficiency virus (HIV)-infected patients, immune reconstitution inflammatory syndrome (IRIS) due to nontuberculous mycobacteria (NTM) infection is one of the most difficult types of IRIS to manage. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has been suggested as a useful tool for evaluating the inflammatory status of HIV-in...

The aim of this retrospective analysis was to describe our clinical experience for fluorine-18 (F) fluorodeoxglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with soft tissue and osseous sarcoma. Total of 26 F-FDG PET/CT scans were evaluated in 17 patients (7 osteosarcoma, 5 Ewing’s sarcoma, 3 uterine sarcoma and 2 rhabdomyosarcoma) in different stages of dise...

A 44-year-old female patient presented symptoms and laboratory data consistent with a Cushing’s syndrome. Endocrine investigations and negative pituitary imaging were suggestive of ectopic ACTH secretion. Therefore, the patient underwent fluorine18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and somatostatin receptor scintigraphy (SRS) searching for the ...

PURPOSE Radiolabeled arginine-glycine-aspartic acid (RGD) peptides have been developed for PET imaging of integrin avβ3 in the tumor vasculature, leading to great potential for noninvasively evaluating tumor angiogenesis and monitoring antiangiogenic treatment. The aim of this study was to investigate a novel one-step labeled integrin-targeted tracer, 18F-AlF-NOTA-PRGD2, for PET/CT for detectin...

This study was aimed to investigate the significance of 18F-FDG PET/CT in secondary hemophagocytic lymphohistiocytosis (sHLH) patients. A total of 18 patients received 18F-FDG PET/CT scan at initial diagnosis. All patients (18/18) had at least 3 organs involved, with increased FDG metabolism in different degrees. Fifteen cases (15/18) had definite underlying diseases, including infections (IAHL...

Multiple myeloma (MM) causes osteolytic lesions which can be detected by 18F-fluorodeoxyglucose positron emission tomography/Computed tomography (18F-FDG PET/CT). We prospectively involve 96 Newly diagnosed MM to take PET/CT scan at scheduled treatment time (figure 1), and 18F-FDG uptake of lesion was measured by SUVmax and T/Mmax. All MM patients took bortezomib based chemotherapy as induction...

Positron Emission Tomography (PET) with 2-deoxy-2-(18F)fluoro-D-glucose ([18F]FDG) is an integral part of the diagnostic workup in patients with suspected or confirmed cancer. The ability of the (18F)FDG-PET study to characterize and detect malignancies can be increased by dual-phase acquisition; this is due to the different kinetics of the radiotracer in the tumor tissue and in the background....

BACKGROUND AND AIMS Retrospectively analyze the sensitivity of 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) in the diagnosis of gastric malignancy compared with gastric endoscopy in persons with nonspecific symptoms and evaluate the necessity of 18F-FDG PET-CT scan before surgery. MATERIALS AND METHODS A total of 53 patients with gastric malignancy ...
