To explore the effectiveness of positron emission tomography (PET) respiratory gating based on time and amplitude to improve the reconstructed image artifacts. It is necessary to appropriately select acquisition and processing methods which ensure the readability of myocardial imaging images in radionuclide medicine myocardial imaging. This summary mainly discusses the identification method and how to avoid adverse effect for images from myocardial imaging process, and includes similarities and differences of varieties methods: identification for image artifacts of myocardial imaging, image reconstruction algorithms and software processing and so on. It should be significant to choose the appropriate method to identify myocardial imaging artifacts in image collection. The pros and cons of myocardial imaging image reconstruction algorithm and various software processing methods still remain unknown. How to choose better appropriate acquisition, image reconstruction and software processing methods for myocardial imaging need further study.%核素心肌显像时,恰当地选用图像采集方式和处理技术能够保证心肌显像图像的可读性.探讨核医学心肌显像中如何避免显像过程可能对图像造成的影响及鉴别方法,其中包括心肌图像伪影的鉴别、图像重建算法以及软件处理的多种方法的异同点.分析发现,对患者图像采集时相应的情况应选用合适的方法鉴别心肌图像伪影,而心肌显像图像重建算法和多种软件处理方法的优劣尚缺乏定论.心肌显像如何更恰当地选用图像采集方式、图像重建和软件处理方法仍有待进一步研究.
