概括
将冠状平面添加到自动乳房超声波 (AB US) 查中,减少了阅读时间,改善了癌症的明显性. 然而,这并没有显著提高检测乳腺癌的诊断性能.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 乳腺癌查 乳腺癌查
背景情况:
- 自动乳房超声波 (AB US) 使用冠状平面进行独特的解剖显示和损伤评估.
- 将冠状平面纳入ABUS乳腺癌查中的诊断价值仍在调查中.
研究的目的:
- 评估在自动化乳房超声波 (AB US) 查中将冠状平面添加到横平面解释的影响.
- 评估诊断性能,病变显著性和阅读时间的变化.
主要方法:
- 对644名女性 (40-70岁) 的ABUS图像进行了回顾性分析,结果各不相同.
- 放射科医生 (新手和经验丰富) 使用横平面 (T平面) 和横加冠状平面 (T+C平面) 解释图像.
- 使用ANOVA对诊断敏感度,特异性,病变明显性和阅读时间进行比较.
主要成果:
- 与单独的T平面 (128s) 相比,T+C平面 (115s) 的平均阅读时间明显更短.
- 癌症的明显性在T+C平面 (OR,1.76;P=.04) 显著更高.
- 在BI-RADS 3或BI-RADS 4值的两个阅读模式之间,没有观察到敏感度或特异性的显著差异.
结论:
- 将冠状平面纳入AB US查可以减少解释时间并改善癌症可见性.
- 在这种情况下,增加冠状平面并不会显著改变乳腺癌检测的整体诊断准确性 (灵敏度和特异性).

179
A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

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...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
