OBJECTIVES To retrospectively evaluate concordance rates and predictive values in concordant cases among multiparametric MR techniques and FDG-PET to grade cerebral gliomas. METHODS Multiparametric MR imaging and FDG-PET were performed in 60 consecutive patients with cerebral gliomas (12 low-grade and 48 high-grade gliomas). As the dichotomic variables,(More)
We investigated the diagnostic performance of 18F-FDG PET and ictal (99m)Tc-HMPAO SPET in pediatric temporal lobe epilepsy (TLE). Twenty-one pediatric TLE patients were enrolled in this study. Their diagnoses were confirmed by histology and post-surgical outcome (Engel class I or II). The patients' ages were 18 or younger (15+/-3 years). Of the 21 patients,(More)
UNLABELLED Adult stem cell therapy is expected to improve left ventricular function in patients with myocardial infarction. Because of the low risk of arrhythmia and the maximal concentration at the target tissue, intracoronary infusion of stem cells is preferred. The aim of this study was to investigate the homing and tissue distribution of intracoronary(More)
PURPOSE The aim of the study was to assess the accuracy of (18)F-fluorodeoxyglucose (FDG) PET/CT in mediastinal lymph node staging of patients with non-small-cell lung cancer (NSCLC) in a region with a high prevalence of granulomatous disease. METHODS Between March 2004 and February 2006, all patients with NSCLC underwent FDG PET/CT and contrast-enhanced(More)
BACKGROUND Metabolic activity assessed by (18)F-fluorodeoxyglocuse-positron emission tomography ((18)F-FDG-PET) reflects biological aggressiveness and prognoses in various tumors. The authors present a correlation between tumor metabolic activity and clinical outcomes in patients with hepatocellular carcinoma (HCC). METHODS Over a 3-year period(More)
BACKGROUND To investigate the utility of CT volumetry for primary gastric lesions in the prediction of pathologic response to neoadjuvant chemotherapy in patients with resectable advanced gastric cancer (AGC). MATERIALS AND METHODS Thirty-three consecutive patients with resectable AGC stage >or=T2 and N1), who had been treated with neoadjuvant(More)
OBJECTIVE Endometrial cancer is the most frequent cancer occurring in the female genital tract in the Western countries. Because surgical staging is currently the standard, noninvasive techniques that accurately identify lymph node (LN) metastases would be beneficial by reducing costs and complications. The purpose of our study is to compare the diagnostic(More)
PURPOSE This study aimed to evaluate the prognostic value of pretreatment (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) in pediatric neuroblastoma patients. METHODS The study included 50 pediatric neuroblastoma patients who underwent diagnostic work-up FDG PET before any treatment. The maximum standardized uptake value (SUV(max)) of(More)
UNLABELLED The (18)F-FDG uptake pattern on PET could be an indicator of the prognosis and aggressiveness of various tumors, including hepatocellular carcinoma (HCC). Hexokinase, especially hexokinase type II (HKII), plays a critical role in (18)F-FDG uptake in rapidly growing tumors. We established a stable cell line overexpressing HKII by the transfection(More)
BACKGROUND The efficacy of intracoronary infusion of granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood stem cells (PBSCs) has not been compared between patients with acute (AMI) versus old myocardial infarction (OMI). In addition, the potential risk of restenosis associated with G-CSF-based stem cell therapy has not been evaluated in(More)
