概括
丹恩的45°视图,大腿骨在45°的曲和20°的绑架,是最敏感的放射位置,用于检测早期大腿骨头骨硬化 (ONFH) 的大腿骨头崩. 这种观点显著改善了与标准放射学相比,ONFH早期诊断.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 生物医学成像技术 生物医学成像技术
背景情况:
- 足骨头骨 necrosis (ONFH) 的准确分期对于治疗规划至关重要,特别是在早期崩阶段.
- 传统放射学使用各种视图,但对于敏感的早期崩检测的最佳位置仍未确立.
- 计算机断层扫描 (CT) 允许在多个位置详细分析股骨头塌.
研究的目的:
- 确定最敏感的放射视图,以检测股骨头骨硬化 (ONFH) 的早期崩.
- 用CT重建图像来比较早期ONFH崩的不同股骨位置的诊断能力.
主要方法:
- 分析了30个带有早期ONFH的部 (10个没有塌,20个有<3mm的塌).
- 从CT扫描中生成了10个重建的前额股骨头图像,这些图像来自不同股骨位置的CT扫描.
- 评估并比较每个位置在检测大腿骨头崩时的灵敏度.
主要成果:
- 在45°曲和20°缩的X射线图显示了检测崩的最高灵敏度.
- 与中性位置 (53%,P < 0.01) 相比,该位置的敏感性显著更高 (86%).
- 在70%的病例中,使用45° flexion和20° abduction视图检测到在标准放射学上错过的塌.
结论:
- 达恩的45度视图 (45度曲,20度绑架) 为早期ONFH崩提供了优越的诊断潜力,而不是标准的前后视图.
- 需要进一步的研究,以充分了解ONFH崩模式,并优化普通X光学检测.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
