[目的]比较CT和MR对于前纵隔肿瘤的诊断准确性。[方法]对比分析127例病理诊断为前纵隔肿瘤患者术前均接受的CT和MR检查影像学表现。[结果]CT诊断符合率61.41%(78/127),MR符合率55.90%(71/127),CT联合MR符合率67.32%(85.5/127)。[结论]对于纵隔肿瘤(胸腺囊肿除外),CT的诊断准确率等同于或更优于MR,CT应作为前纵隔肿瘤首选诊断检查,但对于伴出血或炎症的胸腺囊肿选择MR更加合适。
[Objective] To compare the diagnostic accuracy of CT and MR for anterior mediastinal tumors. [Methods] The imaging manifestations of CT and MR imaging of 127 patients with pre-mediastinal tumors who were diagnosed pathologically were compared and analyzed. [Results] The coincidence rate of CT diagnosis was 61.41% (78/127), MR coincidence rate was 55.90% (71/127), CT coincidence rate was 67.32% (85.5 / 127). [Conclusion] For the diagnosis of mediastinal tumors other than thymus cysts, the diagnostic accuracy of CT is equal to or better than that of MR. CT should be the first choice of diagnosis for anterior mediastinum tumor. However, it is more appropriate to select MR for thymus cyst with hemorrhage or inflammation.
