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。
PET / CT combines positron emission computed tomography (PET) with high sensitive detection performance with X-computed tomography (X-CT) ) Two different performance medical imaging equipment integrated in the same rack, a combination of new multi-modal biomedical imaging equipment and technology, functional imaging and anatomical imaging of the organic combination. PET / CT plays an important role in the diagnosis and differential diagnosis of tumor, staging, curative effect evaluation and prognosis, and is widely used in clinic. The clinical value of PET / CT has been recognized.
