k -空间交错螺旋扫描是一种高效、快速的动态过程成像方法。本文介绍了一种电影版本的交错螺旋成像。该方法克服了传统触发(门控)方法的“闪电”伪影。与分段空间2DFT方法相比,该方法在相当或更短的扫描时间内获得了更好的时间分辨率。初步的人体研究表明,该方法是一种很有前途的动态过程成像工具。
Interleaved spiral scanning ofk‐space is an efficient and fast method for imaging dynamic processes. In this article, a cine version of interleaved spiral imaging is presented. The method is shown to overcome the “lightning‐flash” artifacts of the conventional triggered (gated) method. Compared with the segmentedk‐space 2DFT method, it achieves better temporal resolution in a comparable or shorter scan time. Preliminary human studies show that the method is a promising tool for imaging dynamic processes.
