3D双回声稳定状态与水激发 (3D-DESS-WE) MRI序列有效地可视化了贝尔患者的面部神经变化. 这种成像技术在检测面部神经的病理变化方面表现出高的诊断性能.
科学领域:
- 放射学 放射学是一门学科.
- 神经学 神经学
- 医疗成像医学成像
背景情况:
- 贝尔 (BP) 是面部神经 (FN) 的最常见原因.
- 对FN病理的准确可视化对于诊断和管理至关重要.
研究的目的:
- 评估3D双回声稳定状态与水激发 (3D-DESS-WE) 序列的诊断能力.
- 评估使用3D-DESS-WEMRI的血压患者的FN病理变化的可视化.
主要方法:
- 对30名血压患者和60名对照患者的回顾性分析,使用3D-DESS-WE的3T MRI.
- 对FN信号强度和厚度的定性和定量评估.
- 与对比增强T1WI (CE-T1WI) 的比较以及与临床严重程度的相关性 (Yanagihara分数).
主要成果:
- 与对照组相比,3D-DESS-WE在高血压患者中显示出明显更高的FN信号强度和厚度.
- 定性评估表明了良好的诊断性能 (灵敏度为0.87-0.90,特异性为0.80-0.82).
- 定量指标,特别是受影响与未受影响的厚度比率 (TR_A/U),显示出高的诊断准确性 (AUC 0.908-0.927) 并与临床严重程度相关.
结论:
- 3D-DESS-WE序列是贝尔的常规临床评估的一个有价值的工具.
- 它在可视化与高血压相关的面部神经异常方面提供了高的诊断性能.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
