The authors present the results of a comparative prospective study of the staging 202 bronchogenic carcinomas (T and N) before surgery. The results of CT (202 cases) and MRI (64 cases) were compared with surgical evaluation and pathologic findings. CT and MRI were part of the decisive criteria for therapeutic-surgery choice and were interpreted before surgery. The results showed poor sensitivity for the T and N but better specificity. MRI is superior to CT with the 3 dimensional demonstration and T1 T2 weighted sequences, but its utility remains limited. The authors give their preferred indications for MRI investigation after CT staging. Staging by CT (and MRI) is of great value to avoid impossible thoracotomy and to confirm the findings of mediastinoscopy (suspected N2 and even more N3).
作者展示了一项对202例手术前支气管源性癌（T和N）进行分期的比较性前瞻性研究结果。将CT（202例）和MRI（64例）的结果与手术评估及病理结果进行了比较。CT和MRI是治疗性手术选择的决定性标准的一部分，且在手术前进行解读。结果显示，其对T和N的敏感性较差，但特异性较好。MRI在三维显示及T1、T2加权序列方面优于CT，但其应用仍然有限。作者给出了CT分期后MRI检查的首选适应症。CT（及MRI）分期对于避免无法进行的开胸手术及确认纵隔镜检查结果（怀疑N2甚至更多为N3）具有重要价值。
