概括
磁力共振成像上的骨间带 (SLIL) 信号变化很常见,特别是在老年人中,并且可能并不总是表明急性损伤. 较年轻的患有SLIL变化的患者需要更密切的临床评估,因为偶然发现较少.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 肌肉骨成像系统的成像
背景情况:
- 创伤是斯卡波隆内骨带 (SLIL) 病理的一个已知的原因.
- 许多患有SLIL病理的患者不记得特定的伤害或重复性创伤.
研究的目的:
- 为了确定手腕MRI上的SLIL信号变化的患病率,在各种患者适应症中进行.
- 评估在没有记录的先前手腕创伤的患者中SLIL信号变化的患病率.
主要方法:
- 1021个手腕MRI或MR关节图的回顾性审查.
- 收集关于SLIL信号变化的数据.
- 以年龄为基础的分层分为6组来分析流行率.
主要成果:
- 31%的患者 (317/1021) 显示SLIL信号变化,通常具有较低的临床怀疑 (83%的患者有变化).
- 患病率随着年龄的增长而增加,从15% (18-30岁) 增加到50% (>70岁).
- 51%的患有SLIL变化的患者没有先前的创伤;这个群体的患病率为28% (18-30岁) 到80% (>70岁).
结论:
- 年轻患者的SLIL信号变化可能由于较少的偶然发现而具有更大的临床意义.
- 老年患者中SLIL变化的MRI发现是常见的,可能不代表急性病理.

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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
