Excerpt

In the past few years, myocardial perfusion imaging has significantly evolved with the development of semiconductor cadmium-zinc-telluride (CZT) cameras, leading to a technological jump in this setting. The hopes raised by this new technology have been substantial because of the potential to improve energy resolution and image quality, compared to conventional Anger cameras.1,2 Unlike the latter cameras, these CZT cameras use a principle of direct detection where the interaction of a gamma photon of 140 keV produces approximately 30,000 electrons, a level 20-fold higher than that produced by a sparkling NaI(Tl) crystal.3 One of the most significant consequences is that energy resolution is improved by a factor of 2, compared with conventional Anger cameras. …
