摘要:

目的：探讨MRI与CT在非小细胞肺癌（NSCLC）淋巴结转移诊断中的价值。方法：选取100例NSCLC患者，所有患者术前进行CT和MRI检查，检查结果与病理结果进行比较。结果： 100例患者术中共清除淋巴结758组，平均每例7.58组；有41例发现淋巴转移；MRI诊断淋巴结转移的灵敏度为85.37%、特异度为77.97%、阳性预测值为72.92%、阴性预测值为88.46%；CT诊断淋巴结转移的灵敏度为80.49%、特异度为81.36%、阳性预测值为75.00%、阴性预测值为85.71%；第4R、5、6和7组淋巴结MRI诊断准确率分别为90.77%、94.59%、92.86%和86.00%，明显高于CT检查（P＜0.05）；第9、11和12组淋巴结CT诊断准确率分别为77.22%、88.75%和85.28%，明显高于MRI检查（P＜0.05）。结论：MRI与CT在NSCLC淋巴结转移诊断中，各具有优势，有较强的互补性。

Abstract:

Objective：To explore the value of MRI and CT in the diagnosis of lymph node metastasis in non-small cell lung cancer (NSCLC). Methods: A hundred cases of NSCLC patients were selected in this study, all patients underwent CT and MRI examinations before operation, and the results were compared with pathological results. Results：Sevenhundred and fifty-eightgroups of lymph nodes were removed in this study, with an average of 7.58 lymph per patients; In 100 patients, there were 41 cases with lymph node metastasis. Based on MRI diagnosis of lymph node metastasis, the sensitivity was 85.37%, specificity was 77.97%, the positive predictive value was 72.92%, and the negative predictive value was 88.46%; According to CT diagnosis of lymph node metastasis, the sensitivity was 80.49%, specificity was 81.36%, the positive predictive value was 75.00%, and the negative predictive value was 85.71%; MRI diagnostic accuracy oflymph nodesin groups4, 5, 6 and 7 were 94.59%, 92.86%, 90.77% and 86.00%, significantly higher than CT (P< 0.05);CT diagnostic accuracy of lymph nodes in groups9, 11 and 12 were 77.22%, 88.75% and 85.28%, which were significantly higher than that of MRI (P< 0.05). Conclusion：MRI and CT in the diagnosis of lymph node metastasis in NSCLC have certain advantages, andcould complement each other.
