The high soft tissue contrast and tissue characterization properties of magnetic resonance imaging allow further characterization of indeterminate mediastinal lesions on chest radiography and computed tomography, increasing diagnostic specificity, preventing unnecessary intervention, and guiding intervention or surgery when needed. The combination of its higher soft tissue contrast and ability to image dynamically during free breathing, without ionizing radiation exposure, allows more thorough and readily appreciable assessment of a lesion's invasiveness and assessment of phrenic nerve involvement, with significant implications for prognostic clinical staging and surgical management.
磁共振成像具有较高的软组织对比度和组织特征性，可进一步对胸部 X 线摄影和计算机断层扫描检查中不确定的纵隔病变进行特征描述，提高诊断的特异性，避免不必要的介入，并在需要时指导介入或手术。它具有较高的软组织对比度，并且能够在自由呼吸时动态成像，而不会受到电离辐射的影响，这使得对病变的侵袭性和膈神经受累情况进行更全面、更易于评估成为可能，这对预后临床分期和手术管理具有重要意义。
