| 摘 要： | 本文分析了30例肺癌的 MRI 及手术病理分期的结果。结果表明:MRI 能够比较准确地显示肿块的大小、范围、部位及叶以上支气管的受累情况;容易显示胸壁、纵隔、隔肌及远处转移,对胸壁受侵犯诊断准确率为86.7%;无需使用造影剂能直接显示肺门及纵隔区大血管的受累与否、诊断准确率为83.3%;对肺门及纵隔淋巴结转移诊断准确率为90%,敏感性为91.3%,特异性为85.7%;与手术病理分期结果比较,MRI 对肺癌分期准确率为80%。故认为 MRI 是对肺癌分期癌一种准确的无创性新方法。

| Abstract: | Thirty patients with surgically and pathologically proved bronchogenic carcinoma were per-formed with MRI.MRI and surgical staging of the tumors were compared.It was found:1)MRI isan accurate modality for depicting tumor size,its extension,location and involvement of lobarbronchi and bronchi.2)MRI can easily detect bronchogenic cancinoma with direct extension intochest wall,mediastinum,diaphragm and remote metastases.The accuracy for MRI determining chestwall involvement was 86.7%.3)MRI can directly visualize great vessels in hilar and mediastinumwithout any contrast medium.The accuracy in revealing great vessels involvement with MRI were83.3%.4)The accuracy,sensitivity and specificity for MRI diagnosing hilar or mediastinal lym-phadenopathy were 90%,91.3% and 85.7% respectively.5)Compared with surgery staging,ac-curate rate of staging with MRI was 80%.We preliminarily concluded that MRI is a new reliableand no invasive method for assessment of staging bronchogenic cancinoma. |
