概括
对于接受查性乳腺造影的女性,将2D全场 (FF) 视图与数字乳腺图莫合成 (DBT) 植入物移位 (ID) 视图相结合,可以最大限度地减少辐射剂量,但不会减少癌症检测. 避免使用DBT FF视图来降低辐射暴露.
科学领域:
- 放射学和成像学 放射学和成像学
- 乳房成像 乳房成像
- 在瘤学瘤学.
背景情况:
- 乳房植入患者的查乳房镜像存在独特的成像挑战.
- 数字乳腺图解合成 (DBT) 提供了更好的可视化,但可能会改变辐射剂量和癌症检测率.
- 优化DBT协议对于有效查这一群体至关重要.
研究的目的:
- 在不同基于DBT的成像协议中比较平均腺体剂量 (MGD),癌症检测率 (CDR) 和回忆率 (RR).
- 确定乳房植入物接受乳房扫描的女性的最佳查方案.
- 评估各种DBT和2D数字乳房学组合对成像结果的影响.
主要方法:
- 追溯研究1998年女性的乳房植入物接受查性乳房扫描.
- 使用了DBT和2D数字造乳镜协议的各种组合.
- 收集了关于MGD,植入器细节,乳腺密度,BI-RADS评估,CDR和RR的数据;使用ANOVA和千平方测试进行分析.
主要成果:
- 只有DBT的协议导致MGD最高 (10.29mGy),而只有2D的协议是最低的 (5.88mGy);观察到显著差异 (P < 0.0001).
- 在协议之间没有发现召回率 (RR) 的显著差异 (P = 0.17).
- 组合的2D FF + DBT ID视图协议显示了最高的癌症检测率 (CDR,7.2 / 1000),尽管在协议中没有显著差异 (P = 0.48).
结论:
- 建议将2D FF视图与DBT ID视图结合起来,以使乳腺植入患者尽量减少辐射剂量,而不会影响癌症检测灵敏度.
- 建议在这个患者群体中避免DBT FF视图,以减少辐射暴露.
- 这种优化的协议支持在基于DBT的实践中对乳房植入体的妇女进行有效的查.

X-ray Imaging

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...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
