摘要
目的：探讨18F-FDG PET/CT 显像在诊断食管癌淋巴结转移与病理对照研究价值。方法回顾分析我院食管癌淋巴结转移患者，术前行18F-FDG PET/CT 显像，对转移淋巴结的最大标准摄取值（SUVmax）分析，并与病理结果对照。结果 PET/CT 显像 SUVmax 界值为2.5、5诊断食管癌淋巴结转移的灵敏度、特异性、准确性分别为：69.48%、92.71%、83.33%和87.66%、94.51%、93.26%。结论 PET/CT 显像诊断食管癌转移淋巴结有较高准确性，选择 SUVmax 界值为5对诊断准确性更高。
Abstract
Objective To investigate the 18F-FDG PET / CT imaging in the diagnosis of lymph node metastasis and pathology research value. Methods A retrospective analysis of our hospital lymph node metastasis in patients with preoperative 18F-FDG PET / CT imaging of metastatic lymph nodes in the maximum standard uptake value (SUV max) analysis and compared with pathological findings. Results Of PET / CT imaging SUV max cutoff value of 2.5,5 diagnosis of lymph node metastasis in esophageal sensitivity,specificity,and accuracy were:69.48%,92.71%,83.33% and 87.66%,94.51%,93.26%. Conclusion PET / CT imaging in the diagnosis of lymph node <br> metastasis of esophageal cancer have a higher accuracy, choose SUV max cutoff value of five pairs higher diagnostic accuracy.
