| 摘 要： | 目的：评估脑肿瘤手术后、放疗后的多体素^1H MRS的临床应用价值。方法：21例脑肿瘤手术后、放疗后行多体素^1H MRS检查。结果：^1H MRS显示脑肿瘤内Cho升高5例，其中4例手术证实为肿瘤复发，1例为胶质增生。放射治疗后肿瘤生长抑制。^1H MRS表现为Cho降低，NAA、Cr明显下降。放射性坏死^1H MRS表现为肿瘤坏死区出现乳酸-脂质峰。结论：^1H MRS可评估脑肿瘤术后复发和监测肿瘤放疗后的病理变化，是一种有价值的检查方法。 |

| Abstract: | Objective:To evaluate the clinical application of multi-voxel proton MR spectroscopy in patients with treated brain tumors.Methods:Twenty-one patients with treated brain tumors underwent multi-voxel proton MR spectroscopy.Results:Five patients had elevation of Cho on proton MRS, in which four patients had pathologically-proved recurrent tumors and one had gliosis. Tumor inhibited by radiation had decreased Cho, NAA and Cr on proton MRS.Tumor radiation necrosis showed high Lac-Lip peak on proton MRS.Conclusion:The multi-voxel proton MR spectroscopy was a valuable methods in evaluation of treated tumors and could detect the recurrent brain tumors after operation and pathologic changes of the tumors after radiotherapy. |
