BACKGROUND The objective of the current study was to determine the accuracy of magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT) for detecting lymph node metastases in patients with uterine cervical carcinoma compared with thin-section histopathologic results from systemic lymphadenectomy. METHODS Twenty-two(More)
We performed a retrospective review of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) examination to determine the prevalence of thyroid FDG-PET incidentaloma in a patient group evaluated for metastasis of cancer and in a group of healthy subjects who underwent voluntary cancer screening. We also evaluated the risk of malignancy in focal(More)
PURPOSE The authors analyzed the characteristics of perfusion magnetic resonance imaging (MRI), (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) and (11)C-methionine (MET) PET to compare the efficacies of these modalities in making the distinction between radiation necrosis and tumor recurrence of high-grade glioma. PATIENTS AND METHODS(More)
The aim of this study was to assess the diagnostic accuracy of 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) with respect to lymph node (LN) metastasis in patients with advanced gastric cancer, and to ascertain the factors that affect this accuracy. Seventy-three patients with advanced gastric cancer, verified in all cases by endoscopic(More)
We developed age, gender and ethnic specific brain templates based on MR and Positron-Emission Tomography (PET) images of Korean normal volunteers. Seventy-eight normal right-handed volunteers (M/F=49/29) underwent 3D T1-weighted SPGR MR and F-18-FDG PET scans. For the generation of standard templates, an optimal target brain that has the average global(More)
An imbalance between thrombin and antithrombin III contributed to vascular hyporeactivity in sepsis, which can be attributed to excess NO production by inducible nitric-oxide synthase (iNOS). In view of the importance of the thrombin-activated coagulation pathway and excess NO as the culminating factors in vascular hyporeactivity, this study investigated(More)
The capacity of cells to maintain homeostasis during oxidative stress resides in activation or induction of protective enzymes. Nuclear-factor-E2-related factor (Nrf)-2 as a member of bZIP transcription factors is expressed in a variety of tissues. Transcriptional activation of antioxidant genes through an antioxidant response element (ARE) is largely(More)
UNLABELLED Because (18)F-FDG PET has insufficient sensitivity for the detection of hepatocellular carcinoma (HCC), (11)C-acetate PET has been proposed as another technique for this use. We prospectively evaluated the value of PET/CT using these 2 tracers for the detection of primary and metastatic HCC. METHODS One hundred twelve patients (99 with HCC, 13(More)
OBJECTIVE The aim of this study was to compare magnetic resonance imaging (MRI) with positron emission tomography/computed tomography (PET/CT) in the preoperative detection of lymph node metastases in patients with uterine cervical cancer. STUDY DESIGN This retrospective study reviewed patients with cervical cancer who had undergone both preoperative MRI(More)
BACKGROUND Neoadjuvant chemotherapy for locally advanced breast cancer is a widely accepted treatment. For assessment of the tumor response after chemotherapy, both magnetic resonance imaging (MRI) and (18)F-fluorodeoxyglucose positron emission tomography (PET) are promising methods. PURPOSE To retrospectively compare MRI and PET in the assessment of(More)
