The aim of this study was to assess the scanning technique for covering the whole breast using a commercially available automated breast ultrasonography (US) system.
A total of 40 patients in the supine position underwent automated breast US (ABVS: Siemens Medical Solutions, Mountain View, CA, USA) and hand-held US. The scanning included sequential scans in the upper-outer, lower-outer, lower-inner, and upper-inner regions. After scanning all four segments of each breast using ABVS, hand-held US was performed in all the patients. The detectability of the lesions using the ABVS technique compared with that using the handheld US was evaluated. The average scanning time was compared between any two of the three examiners with various lengths of experience in breast US.
In all, 61 lesions were detected by hand-held US. The average size of the lesions was 7.7 mm (range 2.5-26.0 mm). The number of detected lesions by ABVS was consistent with those found by hand-held US in each patient. The average total scanning time for each examiner using ABVS was 10.9, 11.1, and 11.5 min, respectively. No significant difference was found in the total scanning time between any two of the three examiners.
The four-scans technique for the major segments of the breast is thought to be an operator-independent, feasible method for performing automated breast US.
本研究旨在评估使用商业化自动乳腺超声（ABUS）系统对整个乳房进行扫描的技术。
共 40 例仰卧位患者接受 ABUS（西门子医疗解决方案，美国山景城）和手动超声检查。扫描包括上外侧、下外侧、下内侧和上内侧区域的连续扫描。使用 ABUS 对每个乳房的四个象限进行扫描后，所有患者均进行手动超声检查。评估 ABUS 技术与手动超声检查的病变检出率。比较了具有不同乳腺超声经验的三位检查者之间的任意两种检查方法的平均扫描时间。
共通过手动超声检查发现 61 个病灶。病灶的平均大小为 7.7 毫米（范围 2.5-26.0 毫米）。ABVS 检测到的病灶数量与每位患者通过手动超声检查发现的病灶数量一致。每位检查者使用 ABVS 的平均总扫描时间分别为 10.9、11.1 和 11.5 分钟。三位检查者之间的总扫描时间无显著差异。
认为乳腺主要区域的四象限扫描技术是一种操作独立、可行的 ABUS 检查方法。
