中文摘要：

PET/CT是将具有高灵敏探测性能的正电子发射计算机断层显像（positron emission computed tomography,PET）与能反映精细解剖结构的X-计机算机体层摄影（X-computed tomography,X-CT）两台不同性能的医学影像设备整合在同一个机架,合二为一的多模态生物医学成像新设备与技术,是功能显像和解剖显像的有机结合。PET/CT在肿瘤的诊断与鉴别诊断、分期、疗效评估及预后判断发挥了重要作用,并广泛应用于临床,其临床应用价值已得到认可。

英文摘要：

Positron emission tomography/computed tomography（PET/CT） is the multimodal fusion technology that combines the positron emission tomography（PET） with high detective sensitivity and X-computed tomography（X-CT） which provides detailed anatomical information. This new biomedical imaging scanner is the integration of metabolic and anatomical imaging. PET/CT plays an important role in the diagnosis,differential diagnosis,staging,therapeutic efficacy and prognosis evaluation of tumor. It has been widely used in clinical medicine and the value of clinical application of PET/CT has been widely recognized.
