在3 T下,在志愿者中展示了位于颈总动脉上方的单独标记线圈的功能灌注成像。使用头盔共振器和自旋回波回波平面成像(EPI)序列进行成像,使用内径为6 cm的圆形表面线圈。被用来贴标签。受试者进行手指敲击任务。在受试者中,手指敲击和静息状态之间的信号差异在-0.5%到-1.1%之间。成像方案包括较长的标签后延迟(PLD),以减少通过时间效应。对功能运行的所有重复进行贴标,以缩短采样间隔。Magn Reson Med 49:791-795,2003.© 2003 Wiley利斯公司
Functional perfusion imaging with a separate labeling coil located above the common carotid artery was demonstrated in human volunteers at 3 T. A helmet resonator and a spin‐echo echo‐planar imaging (EPI) sequence were used for imaging, and a circular surface coil of 6 cm i.d. was employed for labeling. The subjects performed a finger‐tapping task. Signal differences between the condition of finger tapping and the resting state were between −0.5% and −1.1 % among the subjects. The imaging protocol included a long post‐label delay (PLD) to reduce transit time effects. Labeling was applied for all repetitions of the functional run to reduce the sampling interval.
