概括
脊椎关节关节缩症 (SCCH) 是一种慢性非细菌性骨炎 (CNO) 的形式,在成年人中使用CT扫描和骨扫描来诊断. 新的标准确定了这种罕见的自身炎症性骨病的关键成像特征.
科学领域:
- 类风湿病学 类风湿病学
- 放射学 放射学是一门学科.
- 核医学就是核医学.
背景情况:
- 硬骨关节关节缩症 (SCCH) 是慢性非细菌性骨炎 (CNO) 的成年表现,是一种罕见的自发炎性轴骨疾病.
- 目前SCCH的诊断标准缺乏明确性,依赖于CT发现的硬化症/高静止症和光学显示增加放射性药物吸收,但需要确定的放射性标记物.
研究的目的:
- 建立明确的成像诊断标准,对成年 CNO 影响椎关节 (SCC) 区域.
- 根据成像发现,区分CNO患者与那些疑似但不存在的CNO患者.
主要方法:
- 一项横截面研究重新评估了来自169名疑似SCC区域CNO患者的CT扫描和全身骨光学扫描.
- 两名骨放射科医生和两名核医生审查了图像,以确认或排除诊断.
- 统计分析比较了已确诊的CNO患者和非CNO对照组之间的成像特征.
主要成果:
- 在118名 (70%) 患者中证实了CNO的诊断,主要是女性,平均年龄为45岁.
- 在CNO患者中,CT的关键发现包括手首硬骨,中间关节骨和第一个肋骨的硬化,以及高静止症和 costoclavicular 带化.
- 增加放射性药物吸收在光阴学上,特别是在 sterni manubrium 观察到 82% 的 CNO 患者.
结论:
- 定义的成像标准,包括CT特征 (硬化症,高静止症) 和光扫描结果 (追踪物吸收),可以可靠地诊断成年CNO.
- 这些标准,重点关注关节,中间关节骨,第一个肋骨和侧关节带,应该提高这种罕见疾病的诊断准确性.
- 这些发现有助于诊断CNO在其早期和晚期阶段,解决以前的诊断陷.

2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

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...
