Our goal was to assess the utility of breathing dynamic cine MR (BDCMR) in the evaluation of tumor invasion to the chest wall in bronchogenic carcinomas.
BDCMR imaging was performed preoperatively in 25 patients with bronchogenic carcinomas adjacent to the chest wall. Twelve sequential images were obtained in the same coronal and/or sagittal planes during one respiratory cycle with fast spoiled GRASS sequence, and analysis with cine-loop display was performed.
In all 14 cases in which free movement of tumor along the parietal pleura on BDCMR was demonstrated, no chest wall invasion was evident at thoracotomy. However, of 11 patients with fixation of the tumor on BDCMR, 5 had benign pleural adhesions, 5 had chest wall invasion at thoracotomy, and 1 with an apical tumor had no benign pleural adhesion or chest wall invasion.
Although BDCMR cannot distinguish benign pleural adhesions from chest wall invasion by tumor, this method accurately estimated the free movement of lung tumors with no invasion of chest wall from bronchogenic carcinomas prior to surgery.
我们的目标是评估呼吸动态电影磁共振成像（BDCMR）在评估支气管源性癌侵犯胸壁方面的效用。
对25例胸壁旁支气管源性癌患者进行术前BDCMR成像。在一个呼吸周期内，使用快速扰相梯度回波序列在相同的冠状面和/或矢状面获取12幅连续图像，并进行电影环显示分析。
在BDCMR上显示肿瘤沿脏层胸膜自由移动的所有14例病例中，开胸手术时未发现胸壁侵犯。然而，在BDCMR上肿瘤固定的11例患者中，5例有良性胸膜粘连，5例在开胸手术时有胸壁侵犯，1例肺尖肿瘤患者既无良性胸膜粘连也无胸壁侵犯。
虽然BDCMR不能区分良性胸膜粘连和肿瘤对胸壁的侵犯，但该方法能准确估计术前支气管源性癌肺肿瘤无胸壁侵犯时的自由移动情况。
