概括
磁共振成像 (MRI) 和CT骨髓造影 (CTM) 在量化椎脊柱狭窄症方面显示出良好的一致性. 然而,MRI可能会高估狭窄的严重程度,轴心MRI图像显示了与CTM的最高一致性.
科学领域:
- 神经外科 神经外科
- 放射学 放射学是一门学科.
- 脊柱成像 - 脊柱成像 - 脊柱成像
背景情况:
- 宫脊髓炎 (CSM) 诊断依赖于像MRI和CTM这样的成像.
- 精确量化脊柱管狭窄和带压缩对于CSM患者的手术前规划至关重要.
研究的目的:
- 为了比较MRI和CTM之间的椎脊柱狭窄和带压缩的定量测量.
- 评估MRI和CTM在确定手术相关狭窄症方面的一致性.
主要方法:
- 50名CSM患者接受了手术前的MRI和CTM.
- 测量道和脊髓尺寸是在两个模式的轴向和斜视图上进行的.
- 应用了手术相关的狭窄值 (<7毫米AP通道直径,>0.8AP线索:通道比率).
主要成果:
- 在MRI和CTM之间观察到很高的一致性 (83-95%),用于狭窄的量化.
- 与CTM相比,MRI发现了更多符合外科标准的水平.
- 轴性MRI图像显示了与CTM用于狭窄检测的最高一致性 (95%).
结论:
- MRI和CTM在量化椎脊柱狭窄症方面表现出良好的一致性.
- 在约12%的评估水平中,MRI可能会高估狭窄症的严重程度.
- 轴性MRI为评估CSM严重性的CTM提供了最高的一致性.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
