PURPOSE The purpose of this work was to compare [18F]2-deoxy-2-fluoro-D-glucose (FDG) PET and 99mTc-methoxyisobutylisonitrile (MIBI) SPECT in the detection of breast cancer and axillary lymph node metastasis in the same patients. METHOD FDG-PET and MIBI-SPECT were performed within 3 days for 40 women (age range 25-86 years old) with suspected breast(More)
UNLABELLED This study evaluated the effect of various beta-adrenergic agonists on (18)F-FDG uptake in brown adipose tissue (BAT) in rats using ex vivo biodistribution studies. METHODS Caffeine (10 mg/kg of body weight, n = 4), ephedrine (5 mg/kg of body weight, n = 4), nicotine (0.8 mg/kg of body weight, n = 9), or a mixture of nicotine and ephedrine (0.8(More)
PURPOSE To investigate the mechanism of enhancement of hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced hepatobiliary phase magnetic resonance (MR) images and to characterize HCC thus enhanced. MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and patient informed consent for research use of the(More)
PURPOSE We retrospectively reviewed FDG-PET/CT images in patients with breast cancer to determine whether PET/CT improved the level of diagnostic confidence as compared with PET and to compare PET/CT and CT findings at the location of suspected malignancies. METHODS The study included 75 patients with known breast cancer. The initial PET/CT study for each(More)
PURPOSE To retrospectively compare fluorine 18 fluorodeoxyglucose (FDG) positron emission tomographic (PET) and computed tomographic (CT) findings at the same anatomic locations in patients with lymphoma by using a combined PET/CT scanner and to analyze the lesions on metabolic and anatomic bases to evaluate causes of discrepant findings between the two(More)
PURPOSE To compare a three-dimensional (3D) T2-weighted turbo spin-echo (TSE) magnetic resonance (MR) sequence (VISTA; Philips Medical Systems, Best, the Netherlands) with a two-dimensional (2D) T2-weighted TSE sequence in terms of image quality, signal intensity (SI) difference ratios, conspicuity, and staging of uterine tumors. MATERIALS AND METHODS(More)
PURPOSE Our aim was to determine dual-phase (18)F-FDG PET imaging features for various subtypes of thymic epithelial tumors based on the World Health Organization classification. METHODS Forty-six patients with histologically verified thymic epithelial tumors [23 with low-risk tumors (4 with type A, 16 with AB, and 3 with B1) and 23 with high-risk tumors(More)
Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas presents in various histopathological stages from benign to malignant lesions. The differentiation between benign and malignant IPMN is important in order to determine the treatment of the patients. However, pre-operative differentiation remains difficult. The aim of this study was to assess the(More)
PURPOSE The aim of this study was to assess the incidence, degree, and predictors of hepatic arterial damage (HAD) after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS A total of 33 patients with unresectable HCC underwent TACE alone using a mixture of iodized oil, epirubicin, and gelatin sponge. A(More)
OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of positron emission tomography (PET) with 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) for staging/restaging, evaluating the treatment response, and screening of recurrence in patients with malignant lymphoma (ML) during long-term follow-up, and to compare that with computer tomography(More)
