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...
PURPOSE The aim of the study was to evaluate the efficacy of 13N-ammonia and 18F-fluorodeoxyglucose (18F-FDG) PET performed on the same day in the detection of advanced prostate cancer (PC) and its metastases. PATIENTS AND METHODS Twenty-six patients with high-risk PC [Gleason score 8-10 or prostate-specific antigen (PSA)> 20 ng/ml or clinical tumor extension ≥ T2c] were recruited into the st...
OBJECTIVE Inflammation is an important contributor to atherosclerosis progression. A glucose analogue 18F-fluorodeoxyglucose ([18F]FDG) has been used to detect atherosclerotic inflammation. However, it is not known to what extent [18F]FDG is taken up in different stages of atherosclerosis. We aimed to study the uptake of [18F]FDG to various stages of coronary plaques in a pig model. METHODS F...
AIM To determine the significance and need for investigation of incidental prostatic uptake in men undergoing 18F-labelled fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for other indications. METHODS Hospital databases were searched over a 5-year period for patients undergoing both PET/CT and prostate magnetic resonance imaging (MRI). For the initial a...
