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~4984 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
