The interpretation of images obtained in the abdomen and pelvis can be challenging, and the coregistration of positron emission tomographic (PET) and computed tomographic (CT) scans may be especially valuable in the evaluation of these anatomic areas. PET-CT represents a major technologic advance, consisting of generally complementary modalities whose combined strength tends to overcome their respective weaknesses. However, this combined functional-structural imaging approach raises a number of controversial questions and presents some unique interpretative challenges. Accurate PET-CT scan interpretation requires awareness of the various pitfalls associated with the imaging components, both individually and in combination. The results of recent PET-CT studies have been very encouraging, but larger prospective studies will be needed to establish optimal hybrid scanning protocols. Applying sound imaging principles, paying attention to detail, and staying abreast of advances in this exciting new modality are necessary for harnessing the full diagnostic power of abdominopelvic PET-CT.
对腹部和盆腔所获图像进行解读可能具有挑战性，而正电子发射断层扫描（PET）与计算机断层扫描（CT）的图像配准在评估这些解剖区域时可能特别有价值。PET-CT代表了一项重大技术进步，由通常互补的成像方式组成，其综合优势往往能克服各自的弱点。然而，这种功能与结构相结合的成像方法引发了一些有争议的问题，并带来了一些独特的解读挑战。准确解读PET-CT扫描需要了解与成像组件相关的各种陷阱，包括单独的组件以及组合在一起的组件。近期PET-CT研究的结果非常令人鼓舞，但需要更大规模的前瞻性研究来确立最佳的混合扫描方案。运用合理的成像原理、注重细节并紧跟这一令人兴奋的新成像方式的进展，对于充分发挥腹盆腔PET-CT的诊断能力而言是必要的。
