心肌灌注成像(MPI)以其在冠状动脉疾病的诊断和预后中的重要价值而被广泛应用于临床。该行业已经为专用心脏SPECT相机开发了创新设计，将整个探测器区域限制为仅对心脏进行成像。还安装了恢复图像分辨率和限制图像噪声的新软件。这些SPECT创新正在缩短研究时间或减少对患者的辐射剂量，促进更容易的日程安排，更高的患者满意度，更重要的是，更高的图像质量。本文介绍了这些以心脏为中心的SPECT软件和硬件创新，为心肌灌注SPECT的持续成功提供了坚实的基础。
Myocardial perfusion imaging (MPI) using nuclear cardiology techniques has been widely applied in clinical practice because of its well-documented value in the diagnosis and prognosis of coronary artery disease. Industry has developed innovative designs for dedicated cardiac SPECT cameras that constrain the entire detector area to imaging just the heart. New software that recovers image resolution and limits image noise has also been implemented. These SPECT innovations are resulting in shortened study times or reduced radiation doses to patients, promoting easier scheduling, higher patient satisfaction, and, importantly, higher image quality. This article describes these cardiocentric SPECT software and hardware innovations, which provide a strong foundation for the continued success of myocardial perfusion SPECT.
