摘 要:Recent novel approaches in myocardial perfusion single photon emission CT(SPECT)have been facilitated by new dedicated high-effi ciency hardware with solid-state detectors and optimized *** protocols include very low-dose(1 mSv)stress-only,two-position imaging to mitigate attenuation artifacts,and simultaneous dual-isotope *** correction can be performed by specialized low-dose systems or by previously obtained CT coronary calcium *** protocols using CT angiography have been *** quality improvements have been demonstrated by novel reconstructions and motion *** SPECT acquisition facilitates dynamic fl ow and early function *** processing algorithms have become automated with virtually unsupervised extraction of quantitative imaging *** automation facilitates integration with clinical variables derived by machine learning to predict patient outcome or *** this review,we describe new imaging protocols made possible by the new hardware *** also discuss several novel software approaches for the quantifi cation and interpretation of myocardial perfusion SPECT scans.
