目的探讨~(18)F-FDG PET/CT在食管癌淋巴结转移诊断中的临床价值。方法在我院随机选取30例食管癌患者,术前均行~(18)F-FDG、PET/CT检查以及胸部CT增强扫描,比较检查食管癌淋巴结转移的准确度。结果 ~(18)F-FDG PET/CT检查发现30例患者中经病理证实,转移淋巴结63个,良性45个。其中~(18)F-FDG PET/CT诊断淋巴结转移的敏感度、特异度、准确度分别为88.41%,94.87%,90.74%,胸部增强CT分别72.46%,87.8%,77.78%.结论 ~(18)F-FDG PET/CT诊断淋巴结转移的敏感度、特异度、准确度均高于增强CT。具有广泛的临床应用价值。
Objective To investigate the clinical value of ~ (18) F-FDG PET / CT in the diagnosis of lymph node metastasis of esophageal cancer. Methods Thirty patients with esophageal cancer were randomly selected in our hospital. All patients underwent F-FDG ~ 18 PET-CT and chest CT scan before operation. The accuracy of lymph node metastasis was compared. Results ~ (18) F-FDG PET / CT examination found that 30 cases of pathologically confirmed 63 lymph node metastases, 45 benign. The sensitivity, specificity and accuracy of ~ (18) F-FDG PET / CT in diagnosis of lymph node metastasis were 88.41%, 94.87% and 90.74%, respectively, and chest CT was 72.46%, 87.8% and 77.78% 18) The sensitivity, specificity and accuracy of F-FDG PET / CT in diagnosis of lymph node metastasis were all higher than those of enhanced CT. Has a wide range of clinical application value.
