BACKGROUND Despite being a relatively rare disease, the incidence of malignant pleural mesothelioma (MPM) is expected to increase over the next two decades due to the long time interval elapsing between exposure to causative factors, mainly asbestos, and disease onset. Early disease stages have been reported to benefit from radical surgery. In more advanced disease stages, a multimodality treat...

Objective: We describe herein two tumor-induced osteomalacia (TIO) cases for whom the causative lesions, located in their popliteal fossa, that were not identi ed in the standard eld of uorine-1818 uorodeoxyglucose positron emission tomography/computed tomography ( F-FDG PET/CT), which usually images only the head, trunk, and proximal parts of the extremities. Clinical Presentation and Interven...

Hepatosplenic candidiasis is a fungal infection, which mostly affects patients with hematologic malignancies such as leukemia. The pathogenesis of this infection is not clear yet, and the liver is the most commonly affected organ. Diagnosis of hepatosplenic candidiasis can be only established via biopsy, since computed tomography (CT) scan, ultrasonography, and magnetic resonance imaging (MRI) ...

AIM 18-Fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) is an imaging modality that is often used to help differentiate benign from malignant pulmonary lesions and it has been shown to be more efficacious than conventional chest computed tomography (CT). However, some benign lesions may also show increased metabolic activity which can lead to false-positive PET...

AIMS To investigate, for a given energy expenditure (EE) rise, the differential effects of glucagon infusion and cold exposure on brown adipose tissue (BAT) activation in humans. METHODS Indirect calorimetry and supraclavicular thermography was performed in 11 healthy male volunteers before and after: cold exposure; glucagon infusion (at 23 °C); and vehicle infusion (at 23 °C). All volunteers...

UNLABELLED The aim of this study was to assess the diagnostic performance of (18)F-FDG PET and integrated (18)F-FDG PET/CT for diagnosing recurrent esophageal cancer after initial treatment with curative intent. METHODS The PubMed, Embase, and Cochrane library were systematically searched for all relevant literature using the key words "(18)F-FDG PET" and "esophageal cancer" and synonyms. Stu...

PURPOSE Polymyalgia rheumatica (PMR) may present together with large vessel vasculitis (LVV), and frequently requires a more intensive therapy. The aim of the study was to evaluate the impact of (18)F-FDG PET/CT in the diagnosis and management of LVV associated to PMR. MATERIAL AND METHODS This prospective study included 40 consecutive patients (27 women/13 men, 68.10±10.27 years) with PMR an...

UNLABELLED Conventional work-up (CWU) with chest radiography, abdominal ultrasonography, and skeletal scintigraphy has limited value in M staging of nonkeratinizing nasopharyngeal carcinoma (NPC). Our aim was to evaluate whether (18)F-FDG PET could replace CWU by comparing their diagnostic efficacies. METHODS Patients with histologically proven nonkeratinizing NPC and no prior treatment were ...

In Hodgkin's lymphoma (HL), PET imaging should be performed in all patients, particularly in stage I or II disease where change in staging will alter management. For aggressive Non-Hodgkin's lymphoma (NHL), PET imaging is valuable to provide a baseline for response evaluation. For indolent NHL, it is concluded that PET imaging is not generally indicated. For HL, a negative FDG-PET scan is highl...

introduction:brain imaging with f-18 fluorodeoxyglucose (18f-fdg) positron ‎emission tomography or tc-99m hexamethylpropyleneamine oxime (‎99mtc-hmpao) spect is widely used for the evaluation of alzheimer's ‎dementia (ad); we aim to assess superiority of one method over the ‎other. methods: twenty four patients with clinical diagnosis of alzheimer disease ‎underwent 18f-fdg pet and ‎99mtc-...
