A 10 years old boy presented to our hospital complaining of belly pain. He had a retroperitoneal mass diagnosed by ultrasound 3 days before. During that time he was found to have slight hypertension. Computed tomography (CT) showed a left retroperitoneal mass with edge enhancement and central necrosis indicating pheochromocytoma (PCC). Vanillymandelic acid (VMA) in the 24 hours urine sample was...

Radiopharmaceuticals (RPC) used for diagnostic and therapeutic purposes in nuclear medicine may contaminate surface areas due to spillage during its preparation or accident RPC transfer from laboratory the treatment room. Fluorine-18 Fluorodeoxyglucose (18F-FDG) is most common positron emission tomography (PET) scan ideal annihilation converted energy at 511 keV short half-life 109.8 min. Ineff...

BACKGROUND Rationalization of antiangiogenics requires biomarkers. Vascular re-normalization is one widely accepted mechanism of action for this drug class. The interstitium of tumors with abnormal vasculature is hypoxic. We sought to track vascular normalization with (18)F-misonidazole ([18F]-FMISO, a probe that detects hypoxia) PET, in response to window-of-opportunity (WoO) treatment with th...

To the Editor: Tuberculosis (TB) has been extensively described in association with various malignancies, especially Hodgkin’s disease (HD) [1]. When TB is accompanying malignant lymphomas is often characterized by an atypical clinical course, with unusual extrapulmonary localizations [2]. Clinical forms of cutaneous TB have been described: These are: the primary TB inoculation, lupus vulgaris ...

INTRODUCTION In the last decade, (18)F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET and PET/CT) has become one of the major diagnostic tools used in oncology. A significant number of patients who undergo this procedure, due to non-thyroidal reasons, present incidental uptake of (18F-FDG) in the thyroid. The aim of the study was to compare the SUVmax (standardized uptake value)...

UNLABELLED In murine models, resection of a primary tumor leads to increased vascularization and accelerated growth of metastases that previously had remained microscopic. To study such a potentially inhibitory effect of primary tumors on the outgrowth of distant metastases in humans, we assessed the metabolic activity of liver metastases by 18F-FDG PET before and after resection of primary col...

Objective: To explore the diagnostic contribution of 18F-FDG-PET/CT in a population patients with classical fever unknown origin (FUO), to pinpoint its place decision tree real-life setting, and identify factors associated 18F-FDG-PET/CT. Method: All adult (aged ? 18 years) diagnosis FUO who underwent an University Hospital Montpellier (France) between April 2012 December 2017 were included. Tr...

To assess the clinical value of dual time point imaging (DTPI) fluorine-18fludeoxyglucose (18F-FDG) positron emission tomography (PET)/CT in differentiating malignancy and benign disease of patients with focally increased gastric uptake.Patients who present focally increased 18F-FDG uptake in gastric wall on conventional PET/CT imaging received delayed imaging. PET/CT scans were acquired at 1 a...
