UNLABELLED The clinical utility of 18F-FDG PET in evaluating salivary gland malignancies has not been well defined. We therefore evaluated the utility of 18F-FDG PET in management for patients with salivary gland cancers. METHODS Thirty-four patients with newly diagnosed salivary gland cancers underwent CT and 18F-FDG PET before surgical resection with radiotherapy. The diagnostic accuracies ...

Whole-body imaging with Positron Emission Tomography (PET) using F-18 Fluorodeoxyglucose (18F-FDG) has been widely used along the evaluation and clinical management of neoplasms. The main advantage whole-body 18F-FDG PET in oncology is ability to detect unexpected or incidental tumor sites. purpose this study was determine incidentaloma examination nuclear medicine. This research uses literatur...

BACKGROUND Hibernoma is a rare, benign, soft tissue tumor arising from brown fat that cannot be distinguished from other lipogenic tumors on computed tomography and magnetic resonance imaging (MRI) scans. On the other hand, the image of hibernoma on 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is different from that of other lipogenic tumors. However, fewer studies have inv...

UNLABELLED Here, we report an experience about 18F-FDG-PET/CT in a patient with an early stage of Idiopathic Retroperitoneal Fibrosis (IRF). At the diagnosis Contrast Enhanced Computed Tomography (CE-CT) revealed periaortic solid tissue in the infrarenal section and locoregional lymph nodes; findings were interpreted as lymphomatous tissue. 18F-FDG-PET/CT showed elevated 18F-FDG uptake in the p...

Pulmonary carcinoids are histologically classified into typical and atypical. It is important to identify these preoperatively for treatment planning and prognosis. Structural imaging cannot conclusively differentiate between them. The aim of this study was to assess the possibility of differentiating the 2 variants using [18F]fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed...

To compare the diagnostic performance of 18F-FDG PET, 11C-FMZ PET, and 11C-FMZ BP imaging for the evaluation of patients with intractable partial epilepsy whose MRI findings are normal by using statistical imaging analysis. Ten patients underwent comprehensive presurgical evaluation, including PET studies, to assess the epileptic foci. The extent of cortical resection was based on the results o...

BACKGROUND The most frequent complications of joint arthroplasty are septic or aseptic loosening of endoprostheses. Preoperative differentiation is essential, since very different treatment methods result from the diagnoses. The aim of the current study was to evaluate the clinical value of 18F-Fluoro-deoxyglucose positron emission tomography (18F-FDG PET) as a diagnostic modality for inflammat...

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 synthes...

Dear Editor, A 40-year-old female presented acutely with syncope and recurrent ventricular tachycardia (VT) requiring repeated cardioversion. Transthoracic echocardiogram (TTE) revealed mildly depressed systolic function of 40% to 45% with normal right ventricular size and function. Coronary angiogram revealed insignifi cant coronary artery disease (CAD). Biopsy of enlarged mediastinal lymph no...

OBJECTIVE The current study was designed to analyze the value of 18F-FDG positron emission tomography/computed tomography (PET/CT) combined with carbohydrate antigen 19-9 (CA19-9) in differentiating pancreatic carcinoma (PC) from chronic mass-forming pancreatitis (CMFP) in Chinese elderly. METHODS As it is impossible to differentially diagnose PC from CMFP, 60 participants older than 65 years...
