【单选题】简述外周神经常用序列: 解析:常规成像可用快速自旋回波(FSE/TSE)T2加权序列,结合反转恢复技术()。 MRN常用SPACE_STIR /CUBE_IR
A.
2加权成像,结合非选择反转脉冲用于抑制脂肪及肌肉信号,具有较高空间分辨率,最新结合抑制血流信号技术,可在平扫时较好抑制血管内信号。静脉给予对比剂后扫描,由于缩短T2值效应,可更好地抑制血管及淋巴组织信号。外周神经也可采用DWIBS背景信号抑制扩散成像:利用弥散加权序列背景被充分抑制,图像有较高对比,但空间分辨率及信噪比较低,且因使用弥散序列,图像畸变较大。近来也有采用DIXON水脂分离技术T2加权成像:利用多回波技术,不同回波水与脂肪内氢质子存在相位差异,计算出水图去除脂肪信号干扰,显示外周神经,受磁场均匀性影响较小。
