“…Discovery NM 530c or 630 (GE healthcare) and D-SPECT (Spectrum Dynamics), equipped with cadmium-zinc-telluride (CZT) detecting elements, are commercially available [35][36][37][38] and a prototype gamma camera: R1-M (Hitachi, Ltd.), equipped with cadmium-telluride detecting elements, is currently being developed [39,40]. Compared with conventional NaI gamma cameras, the CZT gamma cameras have multiple advantages, such as improved spatial resolution, high energy resolution, and high sensitivity which reduces patients' discomfort and minimizes motion artifacts [37,40,41]. However, since the acquisition using the CZT cameras is performed by positioning gamma-ray detectors on the anterior and left lateral side of the thorax, the myocardial SPECT images show noticeable attenuation artifacts in the septal, inferoposterior, and posterolateral wall of the left ventricular myocardium [42].…”

Cardiac single photon emission computed tomography (SPECT)/computed tomography (CT) imaging is facilitated by the dissemination of SPECT/CT hybrid systems and dedicated image fusion software. The combined approach of SPECT and CT has various advantages when compared with stand-alone imaging. CT attenuation correction can correct attenuation artifacts in myocardial SPECT and improves diagnostic accuracy for patients with coronary artery disease (CAD). Cardiac SPECT/CT hybrid imaging allows detection of coronary artery stenoses and abnormalities in myocardial perfusion and fatty-acid metabolism in patients with cardiac disease. It has been reported that this modality improves diagnostic accuracy in the detection of CAD compared to the individual imaging techniques. Furthermore, this approach facilitates the detection of hemodynamically significant coronary artery stenoses and the management of revascularization procedures. These abilities of cardiac hybrid SPECT/CT imaging will be further refined validating a range of clinical applications in large-scale clinical trials.

“…The latest-generation of ultrafast cardiac SPECT scanners equipped with CZT solid-state detectors and improved collimation systems seem to offer better image quality, with higher count sensitivity and superior spatial resolution than with conventional SPECT. 6,7 For myocardial perfusion imaging, this new technology translates into substantial reductions in isotope dose and scan time, 8,9 improved detection of partial thickness myocardial infarcts, 10 and potentially increased sensitivity to detect multivessel disease. 11 However, only limited evidence is currently available to support the use of SPECT for in vivo plaque imaging, and we are not aware of any prospective clinical study that has been conducted to evaluate a SPECT tracer for coronary plaque imaging.…”
