传统的乳腺超声成像是一种低成本、实时和便携的辅助乳腺癌筛查和诊断的方法，对于乳腺组织致密的患者具有特别的好处。我们先前证明，结合基于相干的波束成形另外提高了液体充盈的乳腺肿块和固体乳腺肿块的区别，这是基于委员会认证的放射科医生的定性图像解释。然而，可变的灵敏度(当检测到充满液体的肿块时范围：0.71-1.00)由个体放射科医生阅读器实现。因此，我们提出了两个客观的一致性度量，滞后一一致性(LOC)和一致性长度(CL)，可以在不需要读者评估的情况下定量地确定乳腺肿块的内容。对31个乳腺肿块的数据进行分析。根据每个肿块内的平均或中位数LOC值，在液体充盈的乳腺肿块和实性乳腺肿块之间实现了理想的分离(即1.00灵敏度和特异度)。按CL值均值和中位数分类时，敏感性/特异性分别降至1.00/0.95和0.92/0.89。致密的乳房组织比非致密的乳房组织具有最高的敏感性和特异性。这些结果支持引入一种客观的、不依赖于读者的方法来自动诊断囊性乳腺肿块。
Traditional breast ultrasound imaging is a low-cost, real-time and portable method to assist with breast cancer screening and diagnosis, with particular benefits for patients with dense breast tissue. We previously demonstrated that incorporating coherence-based beamforming additionally improves the distinction of fluid-filled from solid breast masses, based on qualitative image interpretation by board-certified radiologists. However, variable sensitivity (range: 0.71–1.00 when detecting fluid-filled masses) was achieved by the individual radiologist readers. Therefore, we propose two objective coherence metrics, lag-one coherence (LOC) and coherence length (CL), to quantitatively determine the content of breast masses without requiring reader assessment. Data acquired from 31 breast masses were analyzed. Ideal separation (i.e., 1.00 sensitivity and specificity) was achieved between fluid-filled and solid breast masses based on the mean or median LOC value within each mass. When separated based on mean and median CL values, the sensitivity/specificity decreased to 1.00/0.95 and 0.92/0.89, respectively. The greatest sensitivity and specificity were achieved in dense, rather than non-dense, breast tissue. These results support the introduction of an objective, reader-independent method for automated diagnoses of cystic breast masses.
