补充资料：部分饱和序列
部分饱和序列
磁共振成像术语。也称部分饱和恢复序列(partial saturation recovery sequence)。磁共振成像中，间隔一段重复时间(TR)后重复施加90°射频脉冲的序列。第一次90°脉冲后把纵向磁化矢量(Mz)翻转到XY平面上，Mz消失。经过给定的TR后Mz部分恢复，再施加第二个90°射频脉冲，又将Mz翻转到XY平面上。此时的Mz即为给定的TR内纵向弛豫(Mz)的恢复量。这样，在一定的时间范围内重复，Mz随重复时间(TR)的延长呈指数性增长。这种增长主要依赖于T1弛豫和质子密度。用该序列所获的图像为T1加权或质子密度加权像。TR一般应大于T2而小于T1。
