Abstract Background Ewing sarcoma and peripheral primary neuroendocrine tumors are aggressive neoplasms which consist of small, round, blue cells neuroectodermal origin. They usually arise from the skeleton genetic mutations EWSR1 in chromosome 22 FL1 gene on 11. Extraskeletal sarcomas (EES) rare entities with most common sites EES being extremities, head neck region retroperitoneum. Posterior ...

The aim of this study was to evaluate the clinical value of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in advanced liver alveolar echinococcosis (LAE) prior to and following autologous liver transplantation (ALT). The biodistribution of lesions in 8 patients was recorded using 18F-FDG PET/CT prior to and following surgery. The maximum standardized...

A 64-year-old man presented with epigastric discomfort and nausea. Laboratory analyses revealed increased levels of total and direct bilirubin, and increased levels of aminotransferases. Computed tomography revealed the presence of a mass in the distal common bile duct. Endoscopic retrograde cholangiopancreatography and intraductal ultrasonography revealed a 25 mm filling defect in the distal c...

Drug resistance is a major obstacle to cancer cure and may influence [18F]-fluorodeoxyglucose (FDG) incorporation. In this study, glucose transport, hexokinase activity and [18F]-FDG incorporation were measured in drug-resistant tumour cells generated by exposing H630 colon and MCF7 breast cancer cells to increasing concentrations of tomudex (ralt...

Positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) is widely used in the management of lung adenocarcinoma. Pyruvate kinase M2 (PKM2) plays a key role in glycolysis. We therefore investigated whether PKM2 expression affects 18F-FDG uptake in a retrospective analysis of 76 patients who underwent 18F-FDG PET/computed tomography (CT) scans for staging before surgical resectio...

The diagnostic values of diffusion weighted imaging (DWI) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for N-staging of gastric cancer (GC) were identified and compared. After a systematic search to identify relevant articles, meta-analysis was used to summarize the sensitivities, specificities, and areas under curves (AUCs) for DWI and PET/CT. To...

Prostate cancer is the second most common cancer in men worldwide, with a wide spectrum of biologic behavior ranging from indolent low-risk disease to highly aggressive castration-resistant prostate cancer. Conventional imaging with computed tomography, magnetic resonance imaging, and bone scintigraphy is limited for the detection of nodal disease and distant bone metastases. In addition, advan...

BACKGROUND The objective of this study was to evaluate the feasibility and diagnostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and (99m)Tc-methylenediphosphonate (MDP) whole-body bone scanning (BS) for the detection of osteolytic bone metastases. METHODS Thirty-four patients with pathologically confirmed malignancies and suspected osteo...

Purpose: We evaluate the appearances of brain metastases (BMs) detected by magnetic resonance imaging (MRI) small cell lung cancer (SCLC) on 18Fluor-Fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT).
 Patients and methods: SCLC patients who had an 18F-FDG PET/CT scan a MRI within 30 days for initial staging were included. was used to detect BMs. The res...

objective(s): considering the fact that the standardized uptake value (suv) of a normal lung tissue is expressed as x±sd, x+3×sd could be considered as the threshold value to outline the internal tumor volume (itv) of a lung neoplasm. methods: three hollow models were filled with 55.0 kbq/ml fluorine18- fluorodeoxyglucose (18f-fdg) to represent tumors. the models were fixed to a barrel filled w...
