Utilities and Interpretation of ABUS (New Vesion, Invenia) for Breast Ultrasound Screening

Abstract

Automated Breast Ultrasound (ABUS) system was sold by U-systems Inc. from several years ago. And then, the system have developed to Invenia by GE healthcare at 2012. On this year the new Invenia with new workstation system was supplied by GE healthcare. The workstation have a capability to make complete free cross section images by user hope. We can get almost same cross section ultrasound images for all breast area after the examination finished, as that by hand-held ultrasound (HHUS) equipment during examination. Furthermore, we can interpretate the images not only by AP view (as a b-mode by HHUS images) but also CP views. CP view make us to consider the whole breast images and localization the lesion to be diagnosis easily. On the way of the interpretation of Invenia, we think CP view-first and AP view-second is better, because of the good recognition of speculation and architectural distortion, which are some of most important feature for malignancy. And on CP view, I recommend to look for distortion on first, mass on second, other features third. In this presentation, I will show the image of ABUS and HHUS and some pathological images together, to know the utilities and interpretation of ABUS. We think the development of ABUS will change the quality control of breast ultrasound screening.
