摘要 目的应用正电子发射计算机断层成像术/电子计算机X射线断层扫描技术(Positron Emission computed Tomography/electronic Computer X-ray Tomography,PET/CT)探讨呼吸门控采集时采用不同时相对PET图像与CT图像融合的影响。方法将行PET/CT显像发现肺部有结节的14例患者分为两组,应用呼吸门控技术对肺部结节进行不同时相的PET/CT显像,观察PET图像与CT图像的融合合格率。结果时相多的一组,可以得到更好的融合图像,优于时相少的一组。结论 PET/CT采集中,应用呼吸门控技术适当增加采集时相有意义,可以使PET图像与CT图像更好地进行融合,具有较高的临床应用价值,可在临床应用中逐步普及。
