描述了一种运动检测方法，其特别适合于MR光谱成像（MRSI）研究。使用通过其化学位移唯一识别的外部空间参考标记获得关于受试者的平面内旋转和平移的信息。标记位置直接从每个编码步骤获得的数据中获得，并且不需要额外的数据采集。该方法被应用于包括皮下脂质信号的脑H-1 MRSI研究，否则会导致对受试者运动的敏感性增强。
A motion-detection method is described that is specifically suited for MR spectroscopic imaging (MRSI) studies. Information on in-plane rotation and translation of the subject was obtained using external spatial reference markers that are uniquely identified via their chemical shift. The marker locations were obtained directly from the acquired data at each encoding step, and no additional data acquisition was required. This method was applied to brain H-1 MRSI studies that include subcutaneous lipid signals, which otherwise result in enhanced sensitivity to subject motion.
