“…Indeed, normal distribution differences were observed in early studies using CZT cameras and separate specific limits have been recommended for these systems. 7 For quantitative analysis of data obtained with CZT scanners, dedicated normal databases have been created, especially for the Discovery NM 530c (GE Healthcare) [8][9][10] and D-SPECT (Spectrum-Dynamics) 7,11,12 cameras.…”

“…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].…”

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.

“…In multicenter studies, rapid scanning with dedicated cardiac SPECT scanners provided comparable or superior image quality, with a much shorter scan duration than for standard-time scanning with conventional scanners (46,47). However, only one study directly compared low-dose dedicated cardiac SPECT scanning with conventional-dose scanning in the same patients, and one other study simulated low-radiation-dose rest and stress imaging.…”

However, because of a steep growth in MPI in the mid 2000s, concerns about inappropriate use of MPI and imaging-related radiation exposure increased. In response, the professional societies developed appropriate-use criteria for MPI. Simultaneously, novel technology, image-reconstruction software for traditional scanners, and dedicated cardiac scanners emerged and facilitated the performance of MPI with low-dose and ultra-low-dose radiotracers. This paper provides a practical approach to performing low-radiationdose MPI using traditional and novel technologies.
