目的:本研究拟通过优化3.0T场强下,表面相控阵线圈食道高分辨成像的成像参数,以获得高质量的图像,更好地显示食道及周围组织结构,有可能为食道癌术前检查、手术可切除性评价提供进一步的帮助.
目的:比较TSE(Turbo Spin-Echo)-T1WI(T1 Weighted Imaging)和SWI(susceptibility weighted imaging)诊断膝关节半月板撕裂的诊断效果.方法:94名临床疑似膝关节半月板损伤的就诊病人,术前行T1 WI和SWI序列扫描,两名副高以上医师诊断,以关节镜为金标准.
目的:探讨磁共振成像中常见伪影的产生机理与解决方法,以减少MRI检查时产生的伪影,提高MRI图像质量,为临床提供良好的影像诊断资料.方法:应用PHILIPS-1.5T超导型磁共振成像仪,收集我院2008年-2010年135例不同程度和不同类型MRI伪影图像病例,进行回顾性分析,其中,头颈部MR扫描45例,腹部MR扫描33例,脊柱MR扫描25例,四肢MR扫描32例.
目的:回顾性研究表观扩散系数(ADC)及肝胆特异性造影剂莫迪司(GD-PTBOA)对肝硬化结节中的良性再生结节(RN)及发育不良性结节(DN)的应用价值及相关性研究.取得ADC及强化后肝胆摄取期结节信号值对两种结节的诊断敏感率及两种方法的相关性.
目的:通过熟练蒙汉双语者及单汉语志愿者的语言功能磁共振成像,探讨蒙汉双语者及汉语志愿者在汉语词汇信息加工差异的脑机制.词汇命名任务是认知功能障碍常用的测查任务,也是认知神经科学领域中研究词汇形音转换的经典范式.众多研究表明,人脑对不同语种的词汇命名任务的激活区域及强度不尽相同.
