脑白质病变的神经病理学可以通过T-1或t -2加权图像半定量地确定。基于测量的T-1或T-2值的更高水平的量化要么仅限于特定的感兴趣区域，要么仅限于低分辨率地图。由于使用传统技术需要过长的扫描时间，高分辨率的T-1地图难以获得。在本研究中，通过使用单次回波平面成像（EPI）获得临床可接受的图像，其采集方案最大化了信噪比，同时最小化了扫描时间。中国生物医学工程学报，2001,(3):559 - 564。
Determination of neurological pathology in white matter disease can be made in a semiquantitative way from T-1- or T-2-weighted images. A higher level of quantification based on measured T-1 or T-2 values has been either limited to specific regions of interest or to low-resolution maps. Higher-resolution T-1 maps have proved difficult to obtain due to the excessively long scan times required using conventional techniques, In this study, clinically acceptable images are obtained by using single-shot echo planar imaging (EPI) with an acquisition scheme that maximizes signal-to-noise while minimizing the scan time.
