The response surface methodology (RSM) was employed to study the treatment of kaolin suspension by the composite flocculant of MBFGA1 and PAC. And the two quadratic models of the five factors were established with the flocculating rate and floc size as the target responses. The optimal flocculating conditions are MBFGA1 99.75 mg/L, PAC 121 mg/L, pH 7.3,(More)
BACKGROUND Dual-source CT coronary angiography (CTCA) has been used to detect coronary artery disease; however, the factors with potential to affect its diagnostic accuracy remain to be defined. PURPOSE To prospectively evaluate the accuracy of dual-source CTCA in diagnosing coronary artery stenosis according to conventional coronary angiography (CAG),(More)
PURPOSE The purpose of this study was to assess the clinical value of dual-source computed tomography (DSCT) in the detection and dynamic evaluation of the anomalous origin of the right coronary artery originating from the left coronary sinus of Valsalva (ARCAOLS) with an interarterial course. MATERIALS AND METHODS Thirteen patients with ARCAOLS with an(More)
PURPOSE To evaluate feasibility and added value of dual-energy computed tomography (CT) in diagnosis of pulmonary embolism (PE). MATERIALS AND METHODS This institutional animal experimental committee-approved study was performed in accordance with animal care guidelines. Eight New Zealand rabbits underwent standard unenhanced and contrast(More)
PURPOSE To evaluate the diagnostic accuracy of dual-energy computed tomographic angiography (DE-CTA) in the detection of intracranial aneurysms and to determine whether DE-CTA provides adequate information to guide treatment choice. MATERIALS AND METHODS Eighty patients (31 men and 49 women; mean [SD] ages of 52 [9] years) with spontaneous subarachnoid(More)
BACKGROUND Venous thromboembolism (VTE) is one of the most serious complications in membranous nephropathy (MN). We investigate the incidence of VTE in MN patients with nephrotic syndrome (NS). METHODS A total of 100 MN patients with NS were enrolled into this prospective study. The diagnosis of VTE was based on contrast-enhanced dual source computed(More)
PURPOSE To evaluate the feasibility and value of dual-energy computed tomography myocardial iodine maps in the diagnosis of acute myocardial infarction. MATERIALS AND METHODS In 6 dogs, arterial-phase myocardial dual-energy computed tomography imaging were performed 1 day prior to and 3 hours after the surgical ligation of the left anterior descending(More)
PURPOSE To compare virtual non-enhanced liver CT (VNCT) from dual-energy CT (DECT) with true non-enhanced liver CT (TNCT) in patients. METHODS A total of 102 patients underwent multi-phase abdominal CT. Liver arterial VNCT (VNCT(A)) and portovenous VNCT (VNCT(V)) images were derived from the arterial and portovenous DECT data. The mean CT number, signal(More)
OBJECTIVE The purpose of this study was to evaluate the image quality, radiation dose, and diagnostic accuracy of dual-energy CT angiography (CTA) compared with 3D rotational digital subtraction angiography (DSA) in the detection of intracranial aneurysms. SUBJECTS AND METHODS Forty-six patients with clinically suspected intracranial aneurysms underwent(More)
BACKGROUND/AIMS In the injured liver, hepatic stellate cells (HSCs) induce immunosuppression activity and thus participate in the pathogenesis of liver disease, including HCC. Therefore, finding new drugs to inhibit their immunosuppression activity is necessary. This study tests whether bear bile can affect the immunosuppression activities of HSCs. (More)
