The aim of this study was to define the clinical prevalence and rate of malignancy of focal thyroid incidentaloma in a relatively large number of individuals with application of 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) in asymptomatic individuals. The subjects consisted of 4803 physical check-up examinees (2638 men, 2165 women; mean(More)
UNLABELLED The diagnostic accuracy of fused positron emission tomography/computed tomography (PET/CT) was compared with CT alone and PET alone in the staging and re-staging of nasopharyngeal carcinoma (NPC) patients. PATIENTS AND METHODS Eighty-six fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG) PET/CT studies were retrospectively performed in 70 patients(More)
The aim of this study was to evaluate the potential application of 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) for colorectal cancer screening in asymptomatic individuals. The subjects consisted of 3210 physical check-up examinees (1736 men, 1474 women; mean age +/- SD, 53.2 +/- 8 y) with non-specific medical history. In the control(More)
BACKGROUND In recent years, the use of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has become widespread for the staging of lymphoma. In non-Hodgkin lymphoma (NHL), the bone marrow (BM) involvement is a sign of extensive disease, and the iliac crest BM biopsy (BMB) is the established method for the detection of BM(More)
This study examined the association of cholelithiasis post-cholecystectomy with subsequent cancers and evaluated the risk of cancer in patients with both cholelithiasis and cholecystectomy. The Taiwanese National Health Insurance Research Database was used to identify 15545 newly diagnosed cholelithiasis patients from 2000 to 2010, and 62180(More)
OBJECTIVE To determine the risk of osteoporosis in patients with myasthenia gravis (MG) in a large cohort representing 99% of the population of Taiwan. METHODS Data from the Taiwan National Health Insurance Research Database were used to conduct retrospective cohort analyses. The study cohort consisted of 2,073 patients with MG who were 3-fold(More)
BACKGROUND/AIMS To retrospectively evaluate the impact of 18F-fluorodeoxy-glucose-positron emission tomography (FDG-PET) to detect recurrent colorectal cancer based on asymptomatically elevated tumor marker level of carcinoembryonic antigen (CEA). METHODOLOGY Whole-body FDG-PET was performed in 50 patients suspected of having recurrent colorectal cancer(More)
The aim of this study was to evaluate the potential application of 18-fluorodeoxyglucose positron emission tomography (FDG PET) and PET/CT for cancer screening in asymptomatic individuals. The subjects consisted of 3631 physical check-up examinees (1947 men, 1684 women; mean age +/- SD, 52.1 +/- 8.2 y) with non-specific medical histories. Whole-body FDG PET(More)
The purpose of this study was to further localize cerebral perfusion abnormalities, and to better correlate these abnormalities with the clinical severity of Parkinson’s disease (PD). A single-photon emission computed tomography (SPECT) study was performed on 27 patients with PD and 24 age-matched controls. SPECT images were spatially normalized,(More)
