Positron Emission Tomography/Computed Tomography (PET/CT) plays a critical role in managing gastrointestinal (GI) cancers within radiation oncology. It enhances tumor detection, staging, and lymph node involvement assessment, leading to better-targeted radiation treatment. PET/CT also aids in delineating tumor volumes to minimize geographic misses, enabling precise dose escalation to metabolically active regions. Despite its benefits, PET/CT has limitations such as false positives and dependency on complementary imaging. Emerging technologies offer real-time adjustments and personalized treatments, advancing precision medicine in GI radiation oncology. Further research is needed to refine PET/CT integration for improved treatment outcomes and cost-effectiveness.
正电子发射断层扫描/计算机断层扫描（PET/CT）在放射肿瘤学中对胃肠道（GI）癌症的管理起着关键作用。它可提高肿瘤检测、分期及淋巴结受累评估的准确性，从而实现更有针对性的放射治疗。PET/CT还有助于勾勒肿瘤体积，以尽量减少区域遗漏，从而能够精确地增加对代谢活跃区域的剂量。尽管有这些优点，但PET/CT也存在局限性，如假阳性以及对补充成像的依赖性。新兴技术可实现实时调整和个性化治疗，推动了胃肠道放射肿瘤学中的精准医学发展。需要进一步研究以优化PET/CT的整合，从而改善治疗效果和成本效益。
