While some cystic masses can be definitively diagnosed on CT, others remain indeterminate. Because of its intrinsic superior soft tissue resolution, MR is an important tool in the evaluation of select mediastinal masses that are incompletely characterized on CT. This review describes how non-vascular MR provides greater diagnostic precision in the evaluation of indeterminate cystic mediastinal masses on CT. It also emphasizes key MR pulse sequences for optimal evaluation of problematic mediastinal masses.
虽然一些囊性肿块可以在CT上明确诊断，但其他一些肿块仍难以确定。由于其固有的软组织分辨率优势，磁共振成像（MR）是评估某些在CT上特征不完整的纵隔肿块的重要工具。本综述描述了非血管MR如何在评估CT上难以确定的囊性纵隔肿块时提供更高的诊断准确性。它还强调了用于最佳评估有问题的纵隔肿块的关键MR脉冲序列。
