摘　　要：目的探讨18F-2-氟-2-脱氧-D-葡萄糖(18F-FDG)符合线路显像在结直肠癌诊断中的价值及对临床分期的影响。方法对189例临床拟诊结直肠癌患者术前行18F-FDG符合线路显像,原发灶显像结果与术后病理对照,所见转移灶经病理或多种影像学检查及临床随访予以确诊。结果 18F-FDG符合线路显像诊断结直肠癌原发灶的灵敏度、特异度、准确率、阳性预测值和阴性预测值分别为95.9%、70.0%、93.1%、96.4%和66.7%。对远处脏器转移诊断的准确率高,改变12.2%患者的M分期。结论 18F-FDG符合线路显像在结直肠癌原发病灶诊断及术前M分期中有较高价值,可为临床治疗方案的制订提供参考。Objective To evaluate the value of 18F-fluorodeoxyglucose(18F-FDG) coincidence circuit imaging in the diagnosis and staging of colorectal cancer. Methods A total of 189 patients with clinical suspicion of colorectal cancer were diagnosed by 18F-FDG coincidence circuit imaging. The results of the primary tumor were compared with the postoperative pathological findings. The imaging appearance of metastatic cancer was confirmed by pathological diagnosis, other imaging results or clinical follow-up. Results The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 18FFDG coincidence circuit imaging in the diagnosis of primary tumor was 95.9%,70.0%,93.1%,96.4% and 66.7%, respectively.18F-FDG coincidence circuit imaging had a good accuracy in detecting distant lesions, and modified metastasis staging in12.2% patients. Conclusion 18F-FDG coincidence circuit imaging is useful in the diagnosis, metastasis staging and treatment of colorectal cancer.
