Different techniques have been introduced for full automatic processing of myocardial perfusion imaging with single-photon emission tomography. We tried to evaluate the accuracy of one of these commercial automatic processing methods. The study was performed in 300 patients during 18 months. Two post-stress acquisitions in supine and prone positions and one acquisition at rest , were performed for every patient. All images were processed both automatically and interactively and the results were compared to each other. The automatic method matched the interactive method in 95.22% for left ventricle isolation, in 99.54% for excluding extra-cardiac activity and in 98.22% for reorientation of a single projected data. The automatic method was also successful in complete processing of 81.33% sets of stress (supine)-rest and 79.77% sets of stress (prone)-rest images as compared to the interactive method. In conclusion, the fully automated processing method matches the interactive method in complete processing of myocardial perfusion imaging with single-photon emission tomography more than 79.77% and is of equal accuracy to the interactive method in supine and prone-positioned acquisitions.
已经引入了不同的技术用于单光子发射断层扫描心肌灌注成像的全自动处理。我们试图评估这些商业自动处理方法之一的准确性。该研究在18个月内对300名患者进行。每位患者均进行了仰卧位和俯卧位的两次负荷后采集以及一次静息采集。所有图像均进行了自动处理和交互式处理，并将结果相互比较。自动方法在左心室分离方面与交互式方法的匹配率为95.22%，在排除心脏外活动方面为99.54%，在单个投影数据的重新定位方面为98.22%。与交互式方法相比，自动方法在81.33%的负荷（仰卧位）-静息图像组和79.77%的负荷（俯卧位）-静息图像组的完整处理中也取得了成功。总之，全自动处理方法在单光子发射断层扫描心肌灌注成像的完整处理中与交互式方法的匹配率超过79.77%，并且在仰卧位和俯卧位采集中与交互式方法具有同等的准确性。
