摘要

目的:自动乳腺超声系统(ABUS)与乳腺放射摄影筛查的结合提高了癌症检出率;然而,辅助使用 ABUS 增加了召回率。在这项研究中,我们旨在确定一种准确、高效的 ABUS 解释方法,并评估其冠状视图与传统横向视图的潜在实用性:这项回顾性观察研究包括 114 例 ABUS 病例(40 例正常、35 例良性、39 例恶性)。来自多个机构的 10 名医生对匿名冠状切面和横切面进行了独立解读。观察员使用连续量表对每个病例的病变检测信心进行评分,并记录每个冠状切面和横切面解读的阅读时间。采用自由响应接收器操作特征分析比较不同切面的检测准确性;采用配对 t 检验比较平均阅读时间:结果:冠状切面和横切面的检测准确率没有明显差异(优劣值分别为 0.740 和 0.745;P = 0.72)。然而,冠状视图的平均阅读时间明显短于横向视图(每例 149.7 秒对 200.3 秒,p = 0.003):结论:在保持乳腺病变检测准确性的前提下,使用 ABUS 获得的冠状切面有助于解读,与传统的横向切面相比,冠状切面的阅读时间明显更短。

Potential Usefulness a Coronal View using an Automated Breast Ultrasound System in Detecting Breast Lesions.

Objective: An automated breast ultrasound system (ABUS) combined with screening mammography has increased cancer detection rates; however, supplemental ABUS use has increased recall rates. In this study, we aimed to identify an accurate and efficient method of ABUS interpretation and evaluate the potential usefulness of its coronal view versus the conventional transverse view.

Materials and methods: This retrospective observer study included comprised 114 ABUS cases (40 normal, 35 benign, 39 malignant). Ten physicians from multiple institutions interpreted the anonymized coronal and transverse views independently. The observers scored their confidence in the lesion detection for each case using a continuous scale and recorded reading times for each coronal and transverse view interpretation. Free-response receiver operating characteristic analysis was employed to compare detection accuracies between views; a paired t-test was used to compare the average reading times.

Results: Detection accuracy did not differ significantly between the coronal and transverse views (figure of merit=0.740 and 0.745, respectively; p = 0.72). However, the average reading time for the coronal view was significantly shorter than that for the transverse view (149.7 vs. 200.3 seconds per case, p = 0.003).

Conclusion: The coronal view obtained with the ABUS was useful for interpretation and associated with significantly shorter reading times compared with the conventional transverse view while maintaining breast lesion detection accuracy.
