  • 摘要: PET与CT的有机结合实现了解剖显像与功能显像的统一,使得影像诊断能力得到巨大提升,为临床肿瘤的诊断与分期、疗效评价、放疗定位等提供了更为准确的信息。但是要充分发挥PET-CT的诊断优势,并尽可能避免患者受到过多的放射性照射,需制订规范的扫描方案,并严格按照临床指征进行检查。文中讨论了胸、腹部肿瘤的PET-CT扫描方案的设置与选择,如全身或局部扫描、扫描体位、对比剂的应用、呼吸控制、照射剂量的考虑、双时相采集等问题。
    Abstract: Integral PET-CT implemented the unity of anatomy and function. It brings great improvement to the capability of imaging diagnosis and more accuracy information of diagnose and staging, assessment of therapy response and focal localization of radiotherapy on tumors. But it needs to standard the protocols of examination and exam patients according to clinical situation strictly when we have to educe the most diagnostic utility from this imaging modality and avoid the redundant radiant exposure on patients as possible as we can. Discussed some alternative problems about protocols of PET-CT on chest and abdomen tumors such as whole-body or toposcopy, body-position, if contrast agent is need, breathing control, thinking about radiation exposure, dual phase imaging and so on.
