conclusion of the asymptomatic patients investigated, 58% showed focal enhanced periprosthetic glucose metabolism. this finding should be taken into consideration as a more probable unspecific metabolic pattern for correct interpretation of 18f-fdg-pet studies in patients with suspected septic loosening of the hip prosthesis. results fourteen hip prostheses in 12 patients were visually analyzed...

in this case we report the detection of lymph node metastases in a 52 years old patient with mycosis fungoides utilising 18f- fdg-pet/ct which led to a change in the management of the patient.

BACKGROUND Cancer of unknown primary (CUP) is a heterogeneous group of cancers, so called when a biopsy from a patient reveals malignancy without giving a clue to where in the body the primary tumor is located. Whole-body 18-fluorine-fluorodeoxyglucose positron-emission-tomography/computed tomography (18F-FDG PET/CT) is widely used for diagnosis and staging of most cancers. We hypothesized that...

BACKGROUND The role of 18F-fluorodeoxyglucose positron emission computed tomography (18F-FDG PET/CT) is increasing in the diagnosis of polymyalgia rheumatica (PMR), one of the most common inflammatory rheumatic diseases. In addition to other locations, increased 18F-FDG accumulation has been detected in the praepubic region in some patients. However, a deeper description and pathophysiological ...

UNLABELLED The purpose of this study was to retrospectively investigate the feasibility of 11C-choline PET, compared with 18F-FDG PET, for the detection of hepatocellular carcinoma (HCC). METHODS A total of 16 HCC lesions in 12 patients were examined with both 11C-choline PET and 18F-FDG PET. Tumor lesions were identified as areas of focally increased uptake, exceeding that of surrounding non...

BACKGROUND The use of diagnostic 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging for the staging, restaging, and treatment monitoring of melanoma patients has become a well-recognized standard of care. It plays a key role in detecting sites of occult disease and is widely utilized in the medical and surgical planning of such patients. In the cu...

UNLABELLED Chemotherapy is currently the treatment of choice for patients with high-risk metastatic breast cancer. Clinical response is determined after several cycles of chemotherapy by changes in tumor size as assessed by conventional imaging procedures including CT, MRI, plain film radiography, or ultrasound. The aim of this study was to evaluate the use of sequential 18F-FDG PET to predict ...

Stanford University, Department of Radiology, Division of Nuclear Medicine and Molecular Imaging, USA Here we prospectively compared the combined 18F NaF/18F FDG PET/ MRI against 99mTc-MDP in patients with breast and prostate cancers. Twelve patients referred for 99mTc-MDP bone scans were prospectively enrolled from Oct 14 Jan 15. The cohort included 6 men with prostate cancer and 6 women with ...

The use of [18F]-2-FDG has been increasing in recent years. This agent was originally used for evaluation of CNS glucose uptake and pathologic conditions by positron emission tomography (PET). In view of increasing demand for this agent, its production has been started at cyclotron dept., Nuclear research center for agriculture & Medicine-Karaj Iran (NRCAM). In this paper, [18F]-FDG synth...

Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare neoplasms. Herein, we report a case of a 70-year-old man with a hepatic mass. The non-contrast computed tomography (CT) image showed a low-density mass, and dynamic CT images indicated the enhancement of the mass in the arterial phase and early washout in the late phase. F18- fluorodeoxyglucose (18F-FDG) positron emission tomogra...
