Simultaneous dual-isotope SPECT imaging using a cardiac cadmium-zinc-telluride camera with various Technetium-99 m to Iodine-123 ratios
Image quality and correction effects are influenced by <sup>99m</sup>Tc/<sup>123</sup>I ratios, resulting in heterogeneity in the inferior wall of the normal myocardium due to SC. Adjusting kernel parameters of the Gaussian filter or using NC images may help improve image quality when <sup>99m</sup>Tc/<sup>123</sup>I ratios are very high or low.
