数字乳腺图解 (DBT) 引导的核心针活检 (CNB) 与立体 (ST) 引导的CNB相比,减少了手术时间和辐射剂量. 这两种方法对怀疑乳腺异常的诊断准确度都相似.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 乳腺癌的诊断 乳腺癌的诊断
背景情况:
- 数字乳腺图解合成 (DBT) 能够对可疑异常进行直接活检.
- 核心针活检 (CNB) 是乳腺病变的关键诊断工具.
- 将DBT引导和立体 (ST) 引导的CNB进行比较对于优化乳腺活检程序至关重要.
研究的目的:
- 评估和比较ST指导和DBT指导的CNB的性能和结果.
- 评估两种活检指导方法之间的手术时间,辐射暴露和诊断准确性的差异.
主要方法:
- 在2021年8月至2024年7月期间对央行进行的回顾性审查.
- 收集的数据包括图像曝光,平均腺体剂量 (AGD),手术时间和病理结果.
- 使用曼-惠特尼U,独立的t测试,Chi-squared和费舍尔的精确测试进行统计分析.
主要成果:
- 与ST引导的CNB相比,DBT引导的CNB使用的图像曝光次数较少 (1对3),总体AGD较低 (2.09mGy对7.39mGy).
- 使用DBT指导的CNB (571.0s vs. 827.0s) 显著减少了程序时间.
- 在DBT指导和ST指导的CNB之间,在对应率或升级率上没有发现显著差异.
结论:
- 与ST引导的CNB相比,DBT引导的CNB在缩短程序时间,更少的图像曝光和更低的辐射剂量方面具有优势.
- 用DBT引导的CNB保持了与ST引导的CNB可比的诊断准确性.
- 这些发现支持DBT指导的CNB作为乳腺病变活检的高效有效方法.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
