Positron emission tomography (PET) has proved itself to be valuable in the evaluation of patients with a wide array of gastrointestinal (GI) malignancies. Subsequent development of fusion imaging with PET and computed tomography (PET-CT) scanners has significantly advanced the capabilities of imaging by combining the functional data of the(18)F-labeled glucose analogue fluorodeoxyglucose (FDG) with the conventional anatomic data provided by CT. This article reviews the evolving role of FDG PET-CT imaging in the initial assessment and monitoring of GI tumors. Specific applications are discussed, and normal variants and benign findings frequently encountered during PET-CT of the GI tract are reviewed.
正电子发射断层扫描（PET）已证明自身在评估患有多种胃肠道（GI）恶性肿瘤的患者方面具有价值。随后PET与计算机断层扫描（PET-CT）扫描仪融合成像技术的发展，通过将（18）F标记的葡萄糖类似物氟脱氧葡萄糖（FDG）的功能数据与CT提供的传统解剖数据相结合，显著提升了成像能力。本文综述了FDG PET-CT成像在胃肠道肿瘤初始评估和监测中不断演变的作用。讨论了具体应用，并回顾了胃肠道PET-CT检查中常见的正常变异和良性表现。
