| 摘 要： | 临床常规检查方法对结直肠癌术后复发转移的诊断及再分期有一定局限性，^18F-氟脱氧葡萄糖（^18F-FDG）PET作为一种功能代谢显像检查，能早期探测到肿瘤有无复发，准确鉴别术后瘢痕与复发，且能提供全面、准确的再分期信息，有助于制定合理的临床治疗方案，但仍存在假阳性及假阴性诊断。PET-CT融合显像有助于PET图像的正确解释，定位、定性准确度高，应用前景广阔。

| Abstract: | Conventional diagnostic techniques are not very accurate in detection tumor recurrence and restaging tumor. As a functional metabolic imaging modality,18F-fluorodeoxyglucose(18F-FDG) PET can detect tumor recurrence at early stage,accurately differentiate postoperative scar from recurrence,and provide comprehensive information about restaging,but some false positive and false negative exist. Fusion PET and CT can help correctly interpret the PET image,and is accurate in location and diagnosis. Integrated PET-CT will have wider application in tumors. |
