摘要目的对钆塞酸增强后肝胆期MRI在局灶性结节性增生(FNH)及肝细胞腺瘤(HCA)的诊断准确率进行系统回顾及评价。同时确认在肝胆期肝细胞腺瘤呈等或高信号文献报道比例,以及局灶性结节性增生呈高信号的文献报道比例。材料与方法经伦理委员会批准,在多个数据库搜索研究钆塞酸增强MRI用于FNH和HCA鉴别的文章,包括评估诊断准确率的研究。个案报道和病例系列研究也被收集用于分析MR肝胆期HCA呈等或高信号的比例。使用诊断准确性
Abstract Objective To systematically review and evaluate the diagnostic accuracy of gadolinium occlusion in hepatobiliary stage MRI in focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA). At the same time confirmed in hepatobiliary hepatoma adenoma were equal or high signal reported in the literature, as well as focal nodular hyperplasia was reported in the literature of the proportion of high. MATERIALS AND METHODS Approved by the Ethics Committee and searched in multiple databases for articles that investigated the use of gadoxate-enhanced MRI in the identification of FNH and HCA, including studies that assessed the diagnostic accuracy. Case reports and case series studies were also collected to analyze the proportion of equal or high HCA signals in the MR hepatobiliary phase. Use diagnostic accuracy
