In the current issue, Kennedy et al.
1 further validate cadmium-zinc-telluride (CZT) SPECT, including the use of customized databases for automated perfusion scoring. They also demonstrate the utility of CT attenuation correction to reduce false positives and improve diagnostic accuracy. They examined three groups of patients, performing a comparison of CZT and conventional SPECT, establishing a customized database for automated perfusion scoring with CZT, and demonstrating the impact of CT attenuation correction (CTAC) in CZT SPECT. While there have been many studies comparing conventional SPECT to invasive angiography and CZT SPECT to invasive angiography, not many have directly compared them in the same population. …
