BACKGROUND AND PURPOSE To apply a texture analysis of apparent diffusion coefficient (ADC) maps to evaluate glioma heterogeneity, which was correlated with tumor grade. MATERIALS AND METHODS Forty patients with glioma (WHO grade II (n = 8), grade III (n = 10) and grade IV (n = 22)) underwent diffusion-weighted imaging (DWI), and the corresponding ADC maps(More)
Groucho function is essential for Drosophila development, acting as a corepressor for specific transcription factors that are downstream targets of various signaling pathways. Here we provide evidence that Groucho is phosphorylated by the DHIPK2 protein kinase. Phosphorylation modulates Groucho corepressor activity by attenuating its protein-protein(More)
PURPOSE To evaluate the feasibility and effectiveness of endovascular stent-graft repair of infected aortic and arterial aneurysms. METHODS Eight patients (5 men; mean age 56.6 years, range 30-85) with infected saccular aneurysms in the brachiocephalic artery (n=1), proximal descending thoracic aorta (n=1), infrarenal abdominal aorta (n=3), common iliac(More)
PURPOSE To evaluate the potential of xenon ventilation computed tomography (CT) in the quantitative and visual analysis of chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS This study was approved by the institutional review board. After informed consent was obtained, 32 patients with COPD underwent CT performed before the administration(More)
INTRODUCTION We aimed to evaluate the correlation between the size of the solid component on thin-section computed tomography (CT) and invasive component on pathology in small lung adenocarcinomas manifesting as subsolid nodules. METHODS Fifty-nine subsolid nodules in 58 patients were evaluated. The maximum diameters of subsolid nodules and the solid(More)
PURPOSE To describe simple and safe techniques for transurethral removal and for exchange of ureteral stents in female patients under fluoroscopic guidance. MATERIALS AND METHODS During a period of 33 months, the authors removed 4 and exchanged 34 double-J ureteral stents in 17 female patients. Four techniques were implemented to remove or exchange these(More)
PURPOSE To evaluate volume doubling time (VDT) and mass doubling time (MDT) of persistent pulmonary subsolid nodules (SSNs) followed-up with low-dose (LD) computed tomography (CT) in patients without a history of malignancy. MATERIALS AND METHODS This retrospective institutional review board-approved study, with waiver of patient informed consent,(More)
PURPOSE To determine the therapeutic effectiveness and safety of computed tomography (CT)-guided radiofrequency (RF) ablation for hepatocelluar carcinomas (HCCs) that were undetectable at ultrasonography (US). MATERIALS AND METHODS CT-guided RF ablation with use of internally cooled electrodes was performed in 66 patients with 97 HCCs (diameter range,(More)
PURPOSE To evaluate the safety and efficacy of transcatheter arterial chemoembolization used for the treatment of unresectable hepatocellular carcinoma (HCC) with an Asian cooperative prospective study between Japan and Korea. MATERIALS AND METHODS Patients with unresectable HCC unsuitable for curative treatment or with no prior therapy for HCC were(More)
Background/Aims The post-reflux swallow-induced peristaltic wave (PSPW) index and esophageal baseline impedance (BI) are novel impedance parameters used to evaluate esophageal chemical clearance and mucosal integrity. However, their relationship with reflux symptoms is not known. We aim to evaluate the correlations of PSPW index and esophageal BI with(More)
