摘　　要：随着半导体探测器碲锌镉(Cadmium-Zinc-Telluride,CZT)心脏专用单光子发射计算机断层成像(Singlephoton EmissionComputed Tomography,SPECT),即CZT-SPECT的出现,核医学在仪器设备上的发展有了新的突破,以性质稳定的CZT半导体材料直接取代传统的NaI晶体和光电倍增管。CZT半导体组织密度大、原子序数高,因此对SPECT能量探测范围内的光子具有极高的捕获能力,且具有优异的光电性能,是目前γ射线探测器最为理想的半导体材料。技术上的优势有望为CZT-SPECT的临床应用带来更大的研究意义和更高的诊断效能,现对CZT-SPECT在心脏相关疾病方面的应用情况进行综述,以期为其临床应用提供一定的参考价值。With the advent of cadmium-zinc-telluride(CZT)cardiac-specific singlephoton emission computed tomography(CZTSPECT),the development of nuclear medicine has a new breakthrough in the instruments and equipment.It directly replaces traditional NaI crystal and photomultiplier tubes with stable CZT semiconductor materials.CZT semiconductor has high tissue density and atomic number,so it has extremely high capture ability for photons in the energy detection range of SPECT.The excellent photoelectric properties of CZT semiconductor make it the most ideal semiconductor material forγ-ray detectorscurrently available.The technical advantages were bound to bring greater research significance and higher diagnostic efficiency for the clinical application of CZT-SPECT.This paper reviews the application of CZT-SPECT in the heart-related disease,aims to provide reference value for its clinical application.
