The automated breast ultrasound technique has been known for a long time but did not play an important role in diagnostics due to its inferior sensitivity for small solid lesions with low frequency transducers and its uncomfortable examination technique with the patients in a supine position and the breast immersed in water. The automated breast volume scanner (AVBS) is a high-end ultrasound scanner which employs frequencies of 5-14 MHz and consists of a flexible arm with the transducer at the end, a touchscreen and a 3D workstation. The scan is performed with the patient in the prone position. Depending on the breast size, various presettings are available from which the examiner may select the most appropriate. AVBS has various major advantages, such as being independent from the experience of the operator as well as supplying consistent and reproducible results. Additionally, for the first time it became possible to obtain coronal images of the complete breast, which greatly assists the planning of surgical interventions. In this article the ABVS technique will be described and results will be illustrated by means of clinical examples.
自动乳腺超声技术早已为人所知,但由于低频换能器对小实性病变的敏感性较差,且检查技术让患者仰卧、乳房浸入水中,体验不佳,因此在诊断中未发挥重要作用。自动乳腺容积扫描仪(AVBS)是一种高端超声扫描仪,采用5-14MHz的频率,由末端带有换能器的柔性臂、触摸屏和3D工作站组成。扫描时患者需俯卧。根据乳房大小,有多种预设可供检查者选择最合适的。AVBS有诸多主要优点,比如不依赖操作者的经验,且能提供一致、可重复的结果。此外,首次能够获得整个乳房的冠状面图像,这极大地有助于手术干预的规划。本文将描述ABVS技术,并通过临床实例说明结果。
