A novel line scan diffusion imaging sequence (LSDI) is introduced. LSDI is inherently insensitive to motion artifacts and high quality diffusion maps of the brain can be obtained rapidly without the use of head restraints or cardiac gating. Results from a stroke study and abdominal diffusion images are presented. The results indicate that it is feasible to use the LSDI technique for clinical evaluation of acute ischemic stroke. In contrast to echo-planar diffusion imaging, LSDI does not require modified gradient hardware and can be implemented on conventional scanners. Thus, LSDI should dramatically increase the general availability of robust clinical diffusion imaging.
本文介绍了一种新型的线扫描扩散成像序列（LSDI）。LSDI本质上对运动伪影不敏感，无需使用头部固定装置或心脏门控即可快速获得高质量的脑部扩散图。文中展示了一项中风研究的结果以及腹部扩散图像。结果表明，使用LSDI技术对急性缺血性中风进行临床评估是可行的。与回波平面扩散成像不同，LSDI不需要改进梯度硬件，并且可以在传统扫描仪上实现。因此，LSDI将显著提高强大的临床扩散成像的普遍可用性。
