在10名正常志愿者，9名晚期支气管肺癌患者和3名良性胸部异常患者中获得了胸部核磁共振（NMR）图像。在正常志愿者中，纵隔和肺门结构在核磁共振图像和计算机断层扫描上以相同的频率出现。肺门在自旋回波图像上显示得特别好。自旋回波图像显示肿瘤侵犯纵隔，血管和支气管压迫和侵犯，肺门和纵隔淋巴结肿大。肿瘤和良性病变由于T1时间较长，可从纵隔和肺门脂肪中分离出来。在自旋回波图像上可以看到小至1.5cm的肺肿块和结节。核磁共振成像显示出良性和恶性纵隔，肺门和肺异常的评估承诺。
Nuclear magnetic resonance (NMR) images of the thorax were obtained in ten normal volunteers, nine patients with advanced bronchogenic carcinoma, and three patients with benign thoracic abnormalities. In normal volunteers, mediastinal and hilar structures were seen with equal frequency on NMR images and computed tomographic scans. The hila were especially well displayed on spin-echo images. Spin-echo images showed mediastinal invasion by tumor, vascular and bronchial compression and invasion, and hilar and mediastinal adenopathy. Tumor and benign abnormalities could be separated from mediastinal and hilar fat because of their longer T1 times. Lung masses and nodules as small as 1.5 cm could be seen on the spin-echo images. NMR imaging shows promise for assessment of benign and malignant mediastinal, hilar, and lung abnormalities.
