[目的]探讨氟(18F)-氟代脱氧葡萄糖(18F-FDG)双探头符合线路断层融合显像(SPECT/CT)在食管癌诊断中的价值。[方法]149例临床疑诊食管癌患者行18F-FDG双探头符合线路SPECT检查,诊断结果与病理检查结果对照。[结果]149例原发肿块定性诊断的灵敏度、特异性、准确率分别为98.6%(139/141)、75.0%(6/8)、96.6%(139/149);253枚可疑转移淋巴结诊断的灵敏度、特异性、准确率分别为94.4%(201/213)、55.0%(22/40)、84.2%(223/253);56例患者的78个远处病灶中,最终67个病灶被确诊为转移,其灵敏度、特异性、准确率分别为97.0%(65/67)、90.9%(10/11)、96.2%(75/78)。[结论]18F-FDG双探头符合线路SPECT/CT在食管癌治疗前诊断分期上具有较高的准确率和灵敏度,为食管癌术前较好的无创性检查方法。
[Objective] To investigate the diagnostic value of fluorine (18F) -fluorodeoxyglucose (18F-FDG) dual-head coincidence tomography (SPECT / CT) in the diagnosis of esophageal cancer. [Method] 149 cases of suspected esophageal cancer patients underwent 18F-FDG dual-head coincidence line SPECT examination, diagnostic results and pathological examination results. [Results] The sensitivity, specificity and accuracy of 149 cases of primary tumor were 98.6% (139/141), 75.0% (6/8) and 96.6% (139/149) respectively. There were 253 suspicious lymph node metastases The sensitivity, specificity and accuracy were 94.4% (201/213), 55.0% (22/40) and 84.2% (223/253) respectively. Of the 78 distant lesions in 56 patients, the final 67 lesions were The sensitivity, specificity and accuracy were 97.0% (65/67), 90.9% (10/11) and 96.2% (75/78) respectively. [Conclusion] The coincidence line SPECT / CT with 18F-FDG dual-probe coincidence SPECT / CT has a higher accuracy and sensitivity in the diagnosis of esophageal cancer before the treatment, which is a good non-invasive method for preoperative esophageal cancer.
