概括
高分辨率 (HR) 数字乳腺图解合成 (DBT) 显示了比标准分辨率 (SR) DBT更高的癌症检测率 (CDR). 这种改善在先前进行了乳腺造影的患者中更为明显,这表明乳腺癌查效率提高.
科学领域:
- 放射学 放射学是指放射学
- 医疗成像医学成像
- 乳腺癌查 乳腺癌查
背景情况:
- 数字乳腺瘤合成 (DBT) 是乳腺癌查的一个关键工具.
- 不同的DBT系统分辨率可能会影响查结果.
- 现实世界的数据对于评估不同技术的临床实用性至关重要.
研究的目的:
- 为了比较高分辨率 (HR) 和标准分辨率 (SR) 的DBT系统之间的乳腺癌查结果.
- 评估HR与SR DBT对癌症检测率 (CDR),回忆率 (RR) 和回忆的积极预测值 (PPV1) 的影响.
- 评估以前的乳腺造影史对这些结果的影响.
主要方法:
- 在2013-2023年期间对40-79岁的女性进行了回顾性观察队列研究.
- 包括184,006份乳房图 (95,633份SR,88,373份HR) 在内.
- 对混因素进行调整的后勤回归分析,以比较HR和SR DBT之间的结果,包括对以前的乳腺扫描状态的子组分析.
主要成果:
- 与SR DBT相比,HR DBT显示CDR (OR=1.370) 在统计学上显著增加.
- 在HR DBT (OR=1.392) 中,召回率 (RR) 显著高于HR DBT (OR=1.392).
- 回忆的积极预测值 (PPV1) 在HR和SR DBT之间是相似的. 对于先前的乳房镜检查的检查,HR DBT显示显著更高的CDR和RR.
结论:
- 在现实实践中,高分辨率的DBT与较高的癌症检测率有关,而不是标准分辨率的DBT.
- 随着HR DBT的癌症检测增加,特别值得注意的是,在有先前乳房图史的患者中,癌症的检测增加.
- 虽然HR DBT增加了RR,但PPV1仍然可比,这表明在早期癌症检测方面有潜在的好处,但没有显著增加虚假阳性.

Computed Tomography

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...
