概括
骨报告和数据系统 (Bone-RADS) 对于检测恶性光骨病变具有很高的灵敏度,但特异性较低. 骨-RADS的读者间可靠性很好,尽管准确性仍然是对光和硬化损伤的担忧.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 整形外科 整形外科 整形外科
背景情况:
- 孤独性骨损伤需要准确的特征,用于诊断和治疗计划.
- 骨报告和数据系统 (Bone-RADS) 是一种标准化词典,用于CT骨损伤的分类.
- 评估 Bone-RADS 的诊断性能和可靠性对于其临床应用至关重要.

- 评估骨-RADS在CT上单独的骨病变的诊断性能.
- 为了确定骨-RADS分类系统的互读器可靠性.
- 为了比较Bone-RADS的诊断准确性,对于白色骨病变与硬化/混合骨病变.
主要方法:
- 在CT上对179名患有孤独骨损伤的患者进行了回顾性分析.
- 两位放射科医生使用骨-RADS (1=良性,4=恶性) 独立对病变进行了分类.
- 组织病理学结果作为诊断性能计算的参考标准;使用Cohen的kappa评估了读者之间的可靠性.
主要成果:
- 骨-RADS对恶性光性病变具有很高的敏感性 (95%和82%),但对这两种读者都有很低的特异性 (11%).
- 对于硬化/混合性病变,敏感度分别为75%和68%,两种读者的特异性为27%.
- 总体而言,互读器可靠性很好 (κ=0.744),对于光性 (κ=0.565) 和硬化/混合性 (κ=0.851) 病变的一致性中等到非常好.

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...
