Nineteen patients with bronchogenic carcinoma were studied by MR imaging to determine the presence of chest-wall invasion. All studies were carried out at 1.5 T, and the results were correlated with chest radiographs or CT scans. All MR studies were interpreted before surgery (13 cases) and without knowledge of the results of other radiologic studies. MR findings indicative of chest-wall invasion included a high-signal focus within the chest wall and/or chest-wall thickening with increased signal on spin-echo (SE) images having a repetition time of 2500 msec and an echo time of 50-100 msec (SE 2500/50-100). In one case, noncontour-deforming high-signal intensity within chest-wall musculature (but no other abnormality) was demonstrated on SE 2500/50-100 images. Coronal or sagittal imaging facilitated identification of tumor contiguity with extrathoracic structures in apical lesions. Contrast differences between normal and invaded chest wall on T2-weighted images were the most helpful in assessing chest-wall involvement. These preliminary observations indicate that MR imaging is useful in the evaluation of chest-wall invasion by carcinoma of the lung.
对19例支气管源性癌患者进行了磁共振成像（MR）研究，以确定胸壁侵犯情况。所有研究均在1.5T条件下进行，结果与胸部X线片或CT扫描结果进行了对比。所有MR研究均在手术前（13例）进行解读，且解读时不知道其他影像学检查结果。提示胸壁侵犯的MR表现包括胸壁内高信号灶和/或胸壁增厚，在重复时间为2500毫秒、回波时间为50 - 100毫秒的自旋回波（SE）图像上信号增强（SE 2500/50 - 100）。在1例患者中，在SE 2500/50 - 100图像上显示胸壁肌肉组织内有非轮廓变形的高信号强度（但无其他异常）。冠状面或矢状面成像有助于识别肺尖部病变中肿瘤与胸外结构的连续性。T2加权图像上正常胸壁与受侵犯胸壁之间的对比差异对评估胸壁受累最有帮助。这些初步观察表明，MR成像在评估肺癌胸壁侵犯方面是有用的。
