A 58-year-old man with right upper quadrant pain was referred to the radiology department. The patient underwent computed tomography and magnetic resonance imaging, which suggested the diagnosis of gallbladder cancer invading the liver. After surgical removal of the gallbladder, and the adjacent liver parenchyma was performed, the histologic diagnosis of(More)
RATIONALE AND OBJECTIVES To propose a useful computed tomography (CT) criterion, the diameter with compression (DWC), especially in appendices with borderline diameters. MATERIALS AND METHODS We retrospectively collected 216 patients with visible appendices on CT after clinicopathologic confirmation of appendicitis. Each CT criterion of appendicitis was(More)
OBJECTIVES The purposes of this study were to assess retrospectively whether the waveform change during respiration on hepatic vein Doppler sonography is a parameter of severe portal hypertension as estimated by the hepatic venous pressure gradient (HVPG) and to compare with a hepatic vein damping index (DI) at expiration. METHODS Spectral Doppler(More)
Bleeding jejunal varices are rare and could be life threatening. They are usually found in the presence of portal hypertension and prior history of gastrointestinal surgery. They can be effectively managed by radiological interventions such as transjugular intrahepatic portosystemic shunt or transhepatic embolization of varices. However, in patients with(More)
The purpose of this study was to investigate the antioxidant and anti-inflammatory effects of the combined extract of Rhei rhizoma and Coptidis rhizoma (RC-mix) in experimental model of acute reflux esophagitis. The antioxidant activity was assessed by in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(More)
This study aimed to assess and compare sarcopenia with other prognostic factors for predicting long-term mortality in cirrhotic patients with ascites. Clinical data of 65 among 89 patients with measurement of all parameters were consecutively collected. Sarcopenia was evaluated as right psoas muscle thickness measurement divided by height (PMTH) (mm/m).(More)
Branch occlusion of the anterior cerebral artery (ACA) is regarded as a part of Moyamoya disease. The purpose of this study is to define the ACA steal phenomenon (SP) in Moyamoya disease and to evaluate temoporal changes according to the disease progression. From 139 Moyamoya patients we defined ACASP as narrowing of the ipsilateral A1-2 junction while(More)
BACKGROUND & AIMS To assess the correlation between liver stiffness measurement (LSM) by real-time shear wave elastography (SWE) and hepatic venous pressure gradient (HVPG) and to investigate the diagnostic performance of SWE for predicting clinically significant and severe portal hypertension (CSPH and SPH). METHODS Clinical data of 115 cirrhotic(More)
OBJECTIVES The purpose of this study was to investigate the value of liver stiffness in patients without liver disease using shear wave elastography and to determine the liver stiffness threshold value for identifying patients with chronic liver diseases. METHODS A total of 150 patients who underwent liver sonography coupled with shear wave elastography(More)
OBJECTIVES A concern about methotrexate (MTX)-related liver fibrosis in patients with rheumatoid arthritis (RA) is still unresolved. This study investigated the correlation between liver stiffness and the cumulative MTX dose and the risk factors associated with substantial liver fibrosis assessed by real-time shear wave elastography (SWE), a recently(More)
