扫描

The acquisition and post-processing of the spectrum data:all the scannings are compeleted by the MRI of GE Twinspeed 1.5 Ts scanner(GE Medical System, Milwaukee,USA) which has been tested for its data stability before the scannings begin.

波谱数据的采集和后处理：所有的扫描均采用1.5T超导MRI扫描仪(GEMedical System，Milwaukee，USA)完成，机器在扫描前进行数据稳定性的测试。

Participants required more time to shift their focus over the imaged stimulus in the KBR paradigm. More fixations,more saccades,and rarer saccade distance were found when they scanned in the KBR task.Detailed analysis showed that participants scanned the whole distance from the original point to the target point in KBR paradigm,while the scanning distance were much shorter in FP paradigm.

在距离相同的情况下，被试完成KBR任务需要更多的时间，眼动特征表明，被试在完成KBR任务时，需要更多的注视点、眼跳次数和更远的眼跳距离，对眼动轨迹图的分析显示，完成KBR任务时，被试进行的是从初始点到目标点的全程扫描，而完成FP任务时，扫描距离较短。

Methods: The clinical and MRI findins of 21 cases (benign 10 case and malignant 11 cases) of GTN which proved by pathology were retros pectively reviewed, all the patients underwent MR scaning, 16 of 21 cases underwent dynamic contrast-enhanced MR scaning.
