- Mammography sensitivity significantly decreases in extremely dense breasts (43.8%) compared to heterogeneously dense breasts (77.8%).
- Ultrasound shows higher sensitivity (85.3%) and maintains consistent performance across both dense breast types, unlike mammography.
- The area under the ROC curve is 0.89 for ultrasound versus 0.78 for mammography, indicating better overall diagnostic accuracy for ultrasound.
- Ultrasound specificity is 88.4%, slightly lower than mammography's 91.9%, but it significantly improves cancer detection in dense breasts when used together.
- The study concludes that ultrasound is a valuable supplemental imaging tool for breast cancer detection in women with dense breast tissue.
