摘　　要：传统单光子发射计算机体层成像(SPECT)与计算机体层成像(CT)结合使用可显示病灶形态学改变及显像剂分布状态,可提高肿瘤和非肿瘤疾病成像敏感性和特异性。SPECT/CT通过一次成像观察多部位病灶,可用于分析解剖结构及代谢状态,从而提高了疾病鉴别与诊断准确性。新型混合SPECT/CT设备缩短了图像采集时间并提供精准衰减校正和融合成像,为临床合理选择治疗方案提供了科学基础。本文综述了SPECT/CT技术临床应用进展。The combination of conventional single-photon emission computed tomography(SPECT)and computed tomography(CT)may display the morphological changes of lesions and distribution of imaging agents,which is effective to improve the imaging sensitivity and specificity of tumors and non-tumor diseases.SPECT/CT is feasible to analyze the anatomical structure and metabolic status through displaying multi-site lesions with single imaging,thereby improving differential diagnosis and diagnostic accuracy of diseases.In addition,the novel mixed SPECT/CT device shortens the duration of image acquisition and provides precise attenuation correction and fusion imaging,which provides a scientific basis for rational selection of treatment regimens in clinical practice.This review describes the advances in clinical application of SPECT/CT.
