摘要目的为了增强神经的显示,在临床允许的采集时间内,利用3.0 T稳态脂肪和血液抑制技术,开展和评估臂丛神经的MR神经成像。材料与方法该前瞻性研究符合HIPAA,获得伦理委员会批准,签署知情同意书。在相同的参数下使用部分回波联合相位保留的改良同步重建技术,采用改良低聚焦翻转角3D快速自旋回波序列(TSE)同时获得化学位移(Dixon)重建需要的同相位和反相位回波。该多回波TSE改良Dixon序列(mDixon)采用了模拟研究和对3名健
Abstract Objective To develop and evaluate MR nerve imaging of the brachial plexus using 3.0T steady-state fat and blood suppression techniques to enhance the visualization of nerves within the clinically acceptable acquisition time. Materials and Methods This prospective study was conducted in accordance with HIPAA, approved by Ethics Committee, and signed informed consent. The improved synchrotron reconstruction technique with partial echoes and phase preserving under the same parameters is used to obtain the same phase and antiphase bins of Dixon reconstruction by using the modified 3D fast spin echo sequence (TSE) wave. The multi-echo TSE modified Dixon sequence (mDixon) using a simulation study and three health
