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)
BACKGROUND Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RoT) has good postoperative and excellent cosmetic outcomes. To assess the surgical completeness of BABA RoT, it was compared to open thyroidectomy (OT) after propensity score matching of the cohorts. METHODS Between 2008 and 2010, 760 patients who underwent total thyroidectomy 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)
Positron emission mammography (PEM) has been reported to have higher sensitivity than whole-body positron emission tomography (PET)due to higher spatial resolution. However, no direct evidence exists regarding the imaging sensitivity of PEM related to lesion size. In the present study, imaging sensitivity of PEM was investigated in relation to(More)
Preoperative identification of aggressiveness is important for the establishment of a treatment strategy in patients with soft-tissue sarcoma (STS). We compared the predictive values of various metabolic parameters derived from PET/CT with 18F-FDG, including maximal standardized uptake value (SUVmax), total lesion glycolysis (TLG) and metabolic tumour(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)
UNLABELLED We investigated the reproducibility of an automatic quantitative algorithm for measuring regional myocardial wall motion and systolic thickening. METHODS 99mTc-sestamibi gated myocardial SPECT with dipyridamole stress was performed twice consecutively on 31 patients with known or suspected coronary artery disease, with the patients in the same(More)
PURPOSE To assure the surgical completeness of the bilateral axillo-breast approach (BABA) endoscopic thyroidectomy (ET), we compared ET and open thyroidectomy (OT) by means of the radioactive iodine (RAI) uptake of remnant thyroid. MATERIALS AND METHODS From January 2003 to May 2007, 46 patients who had received RAI ablation after total thyroidectomy(More)
The purpose of this study was to investigate the role of 18F-fluorodeoxyglucose (FDG) PET in detecting high-grade meningioma and predicting the recurrence in patients with meningioma after surgical resection. Fifty-nine patients (27 men and 32 women) with intracranial meningioma who underwent preoperative FDG PET and subsequent surgical resection were(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)
