心脏专用碲-锌-镉SPECT仪的技术优势及临床应用进展

Technological advances and clinical application progress of the dedicated cardiac cadmium-zinc- telluride SPECT

心脏专用碲一锌．镉（CZT）SPECT仪近几年实现商品化供应，其较传统SPECT仪的心脏成像质量更佳，空间分辨率及能量分辨率更高，能够缩短采集时间、降低显像剂用量及辐射剂量，目前已逐渐扩大临床应用范围。笔者对CZTSPECT仪的技术优势、临床应用进展及尚存不足进行综述。

The dedicated cardiac cadmium-zinc-telluride （CZT） SPECT device has been commercially applied to the clinics in recent years. Compared to the traditional SPECT, cardiac CZT SPECT has better image quality, higher spatial and energy resolution with shorter acquisition duration and lower radiation exposure. With these advantages, the clinical application of cardiac CZT SPECT is of great potential. This review summarizes the technological advances, clinical progress and current shortages of cardiac CZT SPECT.
