Sun, 12/07/2014 - 14:311039041350老师, 您好!我扫描的静息态数据是15分钟,不知道这个时间可不可以,是否时间太长?如果太长,扫描出来的数据该怎么使用? 应该先扫描结构像还是先扫描功能像,先后顺序是否会对数据结果产生影响? 谢谢,老师~4988 reads

Tue, 11/25/2014 - 23:46yaosir各位老师和同学: 我对扫描参数一直了解不多,最近在写论文时有一些困惑,问题如下: 1. REST的旋转角记录的是标准角,请问标准角是指多少度呢? 2. T1的旋转角记录的是矢状位,这个又是多少度呢? 3. 我们数据的TR是2530(在北师大采的数据),但我看很多研究里面T1的TR是7-8ms,而另一部分则是1000-3000ms,为什么差别这么大呢? 提前感谢!4592 reads
