人们对研究丘脑非常感兴趣，因为它位于大脑的中心位置，是通往高级认知中心的看门人。由于所使用的磁共振序列的噪声对比（CNR），在磁共振中对丘脑单个亚核的成像和测量已被证明是极其困难的。本报告描述了一种被称为皮层衰减反转恢复（CAIR）的新型MR脉冲序列，它增加了图像中的CNR，并允许通过在1.5T下使用反转时间为700 ms的反转恢复序列选择性地消除大脑中的灰质来可视化丘脑的单个亚核。(C) 2000年学术出版社。
There is a significant amount of interest in studying the thalamus because of its central location in the brain and its role as a gatekeeper to higher centers of cognition. Imaging and measuring of the individual subnuclei of the thalamus has proven extremely difficult in MR because of the contrast-to-noise (CNR) of the MR sequences used. This report describes a novel MR pulse sequence known as cortex attenuated inversion recovery (CAIR), which increases the CNR in images and allows the individual subnuclei of the thalamus to be visualized by selectively nulling the gray matter in the brain using an inversion recovery sequence with an inversion time of 700 ms at 1.5T.
