Abstract

The feasibility of using a third energy window (EW) is investigated for rest ²⁰¹Tl/stress ^99mTc scatter corrections in order to obtain improved quantification and image quality compared with dual-isotope myocardial perfusion imaging using two photopeak energy windows (PEWs). To obtain the relationship between the intermediate EW (IEW) and dual-isotope scatter EWs (SEWs), five different EWs, including an IEW between the dual-isotope are used. It is indicated that the crosstalk into each PEW measured with a cardiac phantom is similar in air, however, in water ^99mTc to ²⁰¹Tl crosstalk is greater than twice of that in air. After attenuation and scatter compensation, the qualitative analysis and image quality are improved compared with dual-isotope imaging which used two PEWs, especially with ²⁰¹1 scans acquired in the presence of background activity.
