目的 探讨磁共振神经成像（MRN）技术对骨质疏松性腰椎骨折患者脊神经压迫的诊断效能。方法 选择2019年1月—2022年12月收治的骨质疏松性腰椎骨折患者200例为研究对象,均实施MRN检查,包括腰椎T1WI矢状位、T2WI矢状位、T2WI轴位、短时间反转恢复（STIR）序列、三列-多回波恢复梯度回波（3D-MERGE）序列。以手术结果为“金标准”,分析二者对脊神经压迫的诊断效能。结果 骨质疏松性腰椎骨折患者3D-MERGE序列的信噪比（SNR）、对比度噪声比（CNR）均大于STIR序列（P<0.05）。结论 磁共振神经成像技术对骨质疏松性腰椎骨折患者脊神经压迫的诊断效能显著,利于临床诊治,提升预后效果。

Objective To explore the diagnostic efficacy of magnetic resonance neurography （MRN） technology for spinal nerve compression in patients with osteoporotic lumbar fractures. Methods A total of 200 patients with osteoporotic lumbar fractures admitted to our hospital from January 2019 to December 2022 were selected as study subjects, and all of them underwent MRN examination, including lumbar spine T1WI sagittal, T2WI sagittal, T2WI axial, short-time inversion recovery （STIR） sequence, and three dimensional multiple echo recalled gradient echo （3D-MERGE） sequence. Using the surgical results as the "gold standard", the diagnostic efficacies of both methods for spinal nerve compression were analyzed. Results The signal-to-noise ratio （SNR） and contrast-to-noise ratio （CNR） of the 3D-MERGE sequence in patients with osteoporotic lumbar fractures were higher than those of the STIR sequence （P<0.05）. Conclusion MRN technology has a significant diagnostic efficacy for spinal nerve compression in patients with osteoporotic lumbar fractures, which is beneficial for clinical diagnosis and treatment and improves prognosis.
