抄録
Recently, two vendors have introduced novel SPECT scanners with solid-state semiconductor detectors: Discovery NM530c (D530c) and D-SPECT utilizing the same cadmium zinc-telluride (CZT) detectors, with a different combination of high-sensitivity multi-pinhole or parallel-hole collimator which focuses on the myocardium. The physical performance is dramatically higher than that of conventional Anger cameras, however, 2 CZT cameras are inherently different. Spatial resolution and contrast-to-noise ratio are better with the D530c, whereas detection sensitivity is higher with the D-SPECT. Although 99mTc-labeled myocardial perfusion tracers might not be ideal, estimation of absolute myocardial blood flow or coronary flow reserve using dynamic CZT SPECT is of great interest and a challenging subject.
