对照组受检者单侧肢体运动均可在对侧大脑半球初级运动皮质观察到兴奋区，其最大信号像素时间-信号强度曲线与BLOCK模式运动时相一致。
Signal changes were observed within contralateral primary motor cortex in subjects of control group. The maximal signal pixel time-signal curve was the same to the movement of BLOCK model.
并绘制其时间一信号强度曲线。
The dynamic curves of signal-noise for each case were made and analysed.
结果显示在同一剂量下，不同部位的时间-强度曲线是有变化的。
Results Mean transit time and the distribution volume of the compartment can affect the shape of the time intensity curve at the same dosage.
