BACKGROUND This study was undertaken to evaluate the prognostic value of quantitative metabolic parameters in [(18) F]2-fluoro-2-deoxyglucose (FDG)-positron emission tomography (PET) for diffuse large B cell lymphoma (DLBCL). METHODS A total of 140 DLBCL patients underwent FDG-PET scans before rituximab, cyclophosphamide, doxorubicin, vincristine, and(More)
UNLABELLED The efficacy of cerebral arterial bypass surgery was assessed on brain perfusion SPECT using statistical parametric mapping (SPM) and a probabilistic brain atlas. METHODS Fifteen patients with ischemia in the internal carotid artery (ICA) territory and 21 age-matched healthy volunteers were enrolled. (99m)Tc-HMPAO basal/acetazolamide brain(More)
OBJECTIVES To evaluate the feasibility of 3D perfusion CT for predicting early treatment response in patients with liver metastasis from colorectal cancer. METHODS Seventeen patients with colon cancer and liver metastasis were prospectively enroled to undergo perfusion CT and 18F-FDG-PET/CT before and after one-cycle of chemotherapy. Two radiologists and(More)
CONTEXT There are still some controversies regarding the cutoff value and the influential factors of thyroglobulin (Tg) concentration in washout fluid from fine-needle aspiration (FNA) biopsy (FNA-Tg) on cervical lymph nodes (LNs) in patients with papillary thyroid cancer (PTC). OBJECTIVE Our aims were to validate the cutoff value of FNA-Tg in diagnosing(More)
INTRODUCTION 11C-Methionine (MET) PET and diffusion-weighted (DW) MRI are commonly used for evaluation of gliomas. We assessed the correlation between MET uptake and diffusion restriction measured on DW MRI in glioma. MATERIALS AND METHODS Thirty-one patients with gliomas, who were initially examined with MET PET and DW MRI, were enrolled retrospectively.(More)
INTRODUCTION ALK rearrangement in lung cancer has been identified as a novel molecular target in lung adenocarcinoma. In this study, we evaluated metabolic and metastatic features of lung adenocarcinoma by using FDG PET/CT, with regard to specific genotypes of ALK and EGFR mutation. METHODS Patients with lung adenocarcinoma initially diagnosed and(More)
OBJECTIVE This study was performed to evaluate the clinical value of (18)F-fluorodeoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT) for cancer screening in Korean asymptomatic people. METHODS Between February 2004 and December 2006, 1,587 asymptomatic individuals underwent FDG PET/CT as part of a cancer screening program with(More)
UNLABELLED Although several prognostic factors are used to predict recurrence and to select adequate candidates for liver transplantation for hepatocellular carcinoma (HCC), these prognostic factors have some clinical limitations. The purpose of this study was to evaluate (18)F-FDG PET as a prognostic factor and to optimize its ability to predict tumor(More)
OBJECTIVE To determine the ictal focus and the role of seizure characteristics, fluorodeoxyglucose (FDG) PET, and subtraction ictal SPECT in patients diagnosed as having nonlesional lateral temporal lobe epilepsy by long-term scalp video-EEG monitoring. METHODS The authors studied 33 consecutive patients with nonlesional neocortical epilepsy who had a(More)
OBJECTIVE In the era of targeted therapy for advanced renal cell carcinoma (RCC), appropriate prognosis prediction is necessary for optimal therapy with or without cytoreductive surgery. We evaluated prognostic implication of extrarenal metabolic tumor burden in nephrectomized patients with advanced RCC. METHODS Forty-four patients with advanced RCC who(More)
