概括
新的乳房镜架构扭曲 (MAD) 亚型,辐射扭曲 (RD) 和组织改变 (TA) 在恶性瘤风险和成像发现中显示出显著差异. 这些分类表明观察者之间对于改善乳腺癌检测有很好的一致性.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 乳腺镜架构扭曲 (MAD) 是乳腺癌查中微妙但重要的发现.
- 目前的MAD分类缺乏标准化亚型,这可能会影响诊断准确性和临床管理.
- 区分不同类型的MAD对于准确的风险评估至关重要.
研究的目的:
- 引入和定义两种新型的乳腺造影结构扭曲的亚型:辐射扭曲 (RD) 和非辐射组织改变 (TA).
- 评估这些新定义的RD和TA亚型的临床结果,观察者间的一致性和预测能力.
- 评估特定的乳腺特征与RD和TA的关联以及它们对恶性瘤的预测价值.
主要方法:
- 辐射扭曲 (RD),组织改变 (TA) 和MAD的七个乳腺特征的前性定义.
- 通过三名乳腺放射科医生对89个查合成乳房造影/断层合成检查进行了审查.
- 将MAD分为RD,TA或Neither,然后对临床结果进行分析,观察者之间的协议 (Gwet's AC) 和用于特征预测的后勤回归.
主要成果:
- 在22.5%的案例中,RD被归类为22.5%,在48.3%的案例中被归类为TA,在29.2%的案例中被归类为Neither.
- 恶性瘤的发病率在RD (45%) 与TA (11.6%) 和Neither (0%) 相比显著更高.

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...

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...
