The goal of this study was to investigate the feasibility of detecting invasion of the parietal pleura by lung cancer with inspiratory-expiratory magnetic resonance imaging (MRI). Twenty-three patients with lung cancer in contact with pleura were studied with multisectional MRI during deep inspiration and expiration on the axial and coronal planes. Changes in the tumor's relation relative to the chest wall markers, vertebral bodies, or mediastinal structures were noted. Surgical correlation was available for each case. Twelve tumors were located at the right middle and lower lobes. Five patients who had a significant change in the position of the tumor were found not to have pleural invasion at surgery. The remaining seven tumors without change in their position with respiration were surgically found to invade the parietal pleura. Only 1 of the 11 upper lobe and apical segments of the lower lobe-located tumors showed a change in its position, which had no parietal pleural invasion at surgery. The remaining 10 tumors did not show any movement. Four of them had parietal pleural invasion that were surgically proven, and six tumors had no parietal pleural invasion at surgery. In conclusion, MRI performed during deep inspiration and expiration is a complementary method in detecting parietal pleural invasion for the tumors located in the lower and middle lobes.
本研究的目的是探讨吸气-呼气磁共振成像（MRI）检测肺癌侵犯壁层胸膜的可行性。对23例肺癌累及胸膜的患者在深吸气和呼气时进行了多层面MRI轴位和冠状位扫描。记录肿瘤相对于胸壁标记物、椎体或纵隔结构的关系变化。每例均有手术相关性。12个肿瘤位于右肺中叶和下叶。5例肿瘤位置有明显变化的患者在手术中未发现胸膜侵犯。其余7个呼吸时位置无变化的肿瘤在手术中发现侵犯壁层胸膜。位于上叶及下叶尖段的11个肿瘤中只有1个肿瘤位置有变化，其在手术中无壁层胸膜侵犯。其余10个肿瘤未显示任何移动。其中4个经手术证实有壁层胸膜侵犯，6个肿瘤在手术中无壁层胸膜侵犯。总之，深吸气和呼气时进行的MRI是检测下叶和中叶肿瘤壁层胸膜侵犯的一种补充方法。
