BACKGROUND Hypoxia up-regulates vascular endothelial growth factor (VEGF) and stimulates the growth of hepatocellular carcinoma (HCC) cells. This study was designed to investigate the association between changes in plasma VEGF levels after transcatheter arterial chemoembolization (TACE) and HCC progression, especially in relation to metastasis. METHODS(More)
OBJECTIVE To investigate the therapeutic efficacy of uterine artery embolization in the treatment of uterine fibroids and to analyse the influential factors to the therapeutic efficacy. METHODS Thirty-two patients with symptomatic uterine myomas were treated by superselective catheterization and embolization of bilateral uterine arteries using PVA(More)
OBJECTIVE To investigate liver lobe volumes and the ratios of liver lobe volumes to spleen volume measured with magnetic resonance imaging (MRI) for quantitatively monitoring and staging liver fibrosis. METHODS Animal study was approved by Institutional Animal Care and Use Committee. Sixteen minipigs were prospectively used to model liver fibrosis, and(More)
OBJECTIVE To investigate the relation between changes in serum vascular endothelial growth factor (VEGF) level after transcatheter arterial chemoembolization (TACE) and hepatocellular carcinoma (HCC) progression, especially in relation to metastasis. METHODS Serum VEGF expression level, measured by quatitative sandwich enzyme-linked immunosorbent assay(More)
Gd-EOB-DTPA is a newly developed liver specific magnetic resonance contrast agent, which is widely used for focal liver lesion (FLL) detection and liver function evaluation. However, it has been demonstrated that hepatocytes uptake of Gd-EOB-DTPA obviously decreased in cirrhotic liver, and cirrhotic liver parenchyma may show reduced enhancement in(More)
OBJECTIVE To evaluate the effectiveness and method of the large-diameter balloon dilation in the treatment of esophageal achalasia. METHODS The hydrophilic guide wire and Wilson-Cook's Savary-Gilliard dilators were inserted into the stomach through the oral cavity under fluoroscopy. The Boston's balloon (35 mm in diameter) was introduced to the stricture(More)
Cerebral blood flow is strongly associated with brain function, and is the main symptom and diagnostic basis for a variety of encephalopathies. However, changes in cerebral blood flow after mild traumatic brain injury remain poorly understood. This study sought to observe changes in cerebral blood flow in different regions after mild traumatic brain injury(More)
Magnetic resonance imaging (MRI) contrast agents are categorised according to the following specific features: chemical composition including the presence or absence of metal atoms, route of administration, magnetic properties, effect on the magnetic resonance image, biodistribution and imaging applications. The majority of these agents are either(More)
