目的探讨18F-FDG符合线路显像在食管癌淋巴结及远处转移分期中的价值。方法45例食管癌患者行18F-FDG符合线路显像,并与同期CT及术后病理作比较。结果18F-FDG符合线路显像对食管癌淋巴结转移的诊断特异性及阳性预测值优于CT,对食管癌周围组淋巴结诊断特异性及食管癌非肿瘤周围组淋巴结转移诊断特异性、阴性预测值及准确性优于CT。18F-FDG符合线路显像发现7例远处转移。结论18F-FDG符合线路显像对食管癌淋巴结转移判断有一定临床价值,对食管癌的术前分期、治疗方案的制订有重要的临床应用价值。
Objective To investigate the value of 18F-FDG coincidence imaging in lymph node metastasis and distant metastasis of esophageal cancer. Methods 45 cases of esophageal cancer patients underwent 18F-FDG coincidence line imaging, and compared with the same period CT and postoperative pathology. Results The diagnostic specificity and positive predictive value of 18F-FDG coincidence imaging for lymph node metastasis of esophageal cancer was better than that of CT. The diagnostic specificity of the 18F-FDG coincidence imaging and the lymph node metastasis of non-tumor surrounding esophageal cancer were negative predictive value And the accuracy is better than CT. 18F-FDG line imaging found 7 cases of distant metastasis. Conclusion 18F-FDG coincidence line imaging has certain clinical value in judging lymph node metastasis of esophageal cancer, and has important clinical value for the preoperative staging and treatment planning of esophageal cancer.
