概括

三维 (3D) 磁共振 (MR) 骨髓录显著改善脑脊液 (CSF) 泄漏的显著性和图像质量,而不是2D MR骨髓录. 这使得3DMR骨髓造影成为诊断脊髓中核液泄漏的更可靠工具.

科学领域:

放射学放射学是指放射学
医疗成像医学成像
神经学神经学

背景情况:

脊髓脑脊液 (CSF) 泄漏的诊断可能具有挑战性.
精确的CSF泄漏的可视化对于有效的治疗至关重要.

研究的目的:

为了比较3D和2D磁共振 (MR) 骨髓学之间的CSF泄漏的明显性和图像质量.
为了确定3DMR骨髓图的可靠性,用于识别脊髓中枢神经液的泄漏.

主要方法:

18名脊髓中核液泄漏的患者接受了3次特斯拉核磁共振成像.
三名放射科医生使用4分级评价了CSF泄漏的明显性和图像质量.
使用并排比较和读者之间的协议 (Gwet的AC1) 来评估性能.

主要成果:

与2D相比,3DMR骨髓图显示,与2D相比,CSF泄漏明显更好 (3.3对1.9,p < 0.0001),并减少了CSF流动器件 (1.0对2.5,p = 0.0001).
78-83%的读者认为3DMR骨髓图比2D高.
读者之间的一致性几乎是完美的3D核磁共振骨髓学 (AC1 = 0.85-1.00).

结论:

与2D技术相比,3DMR骨髓图提供了较好的CSF泄漏可视化.
增强的可见性和图像质量使得3DMR骨髓造影成为诊断脊髓中核液泄漏的更可靠方法.

关键词:

在3D成像中使用3D成像.在 MR 骨髓造影中,这就是为什么MRI是MRI.脊髓大脑脊髓液泄漏脊髓大脑脊髓液泄漏自发的内低血压.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

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...
