A total of 93 patients with pulmonary diseases were examined by means of magnetic resonance tomography. Of these, 39 had a bronchial neoplasm of varying histological structure and varying hilar and mediastinal extension. Compared with other imaging methods, magnetic resonance tomography offers advantages in the imaging of a malignant process and accurate definition of its spatial extension. MR and CT seem to be essentially of equal value in respect of the diagnostic problem of deciding whether lymph node metastases are present in the mediastinum and in the hilus. On the other hand, CT is presently still superior to MR with regard to verifying small-scale processes which are in the process of undergoing endobronchial growth, since CT provides better spatial resolution. Hence, in our opinion the special value of magnetic resonance tomography is the exact definition of the extension of an already identified neoplastic process. This method can supply accurate pointers towards the operability of a bronchial neoplasm. In this regard it is an ideal complement to mediastinoscopy. However, MR will not be an important tool--even in the foreseeable future--for effecting early diagnosis of a neoplasm. The value of diagnostic information supplied by this method may improve by the future use of breath triggering, and additional diagnostic advantages are envisaged by the use of contrast media and the future possibility of producing thinner layers. That is why the catalogue of indications prepared at this time should be seen as a kind of momentary snapshot which may have to be supplemented or extended after the prevailing technical and equipment parameters have undergone further optimisation.
共有93例肺部疾病患者接受了磁共振断层扫描检查。其中,39例患有组织学结构各异、肺门和纵隔侵犯程度不同的支气管肿瘤。与其他成像方法相比,磁共振断层扫描在恶性病变成像及其空间侵犯范围的精确界定方面具有优势。在判断纵隔和肺门是否存在淋巴结转移这一诊断问题上,磁共振成像(MR)和计算机断层扫描(CT)的价值似乎基本相当。另一方面,在证实正处于支气管内生长过程的小范围病变方面,CT目前仍优于MR,因为CT具有更好的空间分辨率。因此,我们认为磁共振断层扫描的特殊价值在于对已确诊肿瘤病变范围的精确界定。该方法可为支气管肿瘤的可切除性提供准确依据。就此而言,它是纵隔镜检查的理想补充。然而,即使在可预见的未来,MR也不会成为肿瘤早期诊断的重要工具。通过未来使用呼吸触发技术,该方法提供的诊断信息价值可能会提高,并且使用造影剂以及未来能够生成更薄层图像有望带来更多诊断优势。这就是为什么此时制定的适应证目录应被视为一种临时快照,在当前技术和设备参数进一步优化后可能需要补充或扩展。
