Titles and abstracts of search results were examined. The following search terms were used: automated breast ultrasound/ultrasonography, automated breast volume scanner/scanners/scanning, and automated whole breast ultrasound/ultrasonography artifacts. In the present review, we performed a computerized search by using the PubMed database ( accessed on 30 April 2021), including articles listed up to 30 April 2021. The aim of this paper is to review the advantages and drawbacks of ABUS and also to illustrate the main artifacts that could limit the diagnosis. Therefore, this technique was developed in order to standardize breast ultrasound and to eliminate some limitations of hand-held ultrasounds (HHUS), such as operator dependence and time of examination. In addition, coronal reconstructions bring new diagnostic information. ABUS is a technique that separates the moment of image acquisition (made by the radiographer) from the moment of image interpretation, thus reducing the operator-dependence, as well as the time spent by the physician. The authors found that ABUS could detect breast cancer with a clinically insignificant decrease in specificity compared to screening mammography alone (76.2% vs. A total of 17 radiologists first interpreted the mammograms alone and then interpreted the combined mammography and ABUS. The study included 164 cases, 133 non-cancers and 31 biopsy-proven cancers. Approval became possible after the U-Systems pivotal clinical retrospective multi-reader study. Īutomated breast ultrasound (ABUS) represents a new imaging technique approved by the Food and Drug Administration (FDA) in 2012 as a supplemental screening tool for women with heterogeneously and extremely dense breasts. Therefore additional imaging modalities are required to improve cancer detection. Dense glandular tissue is an independent risk factor in the development of breast cancer, the risk being 6–8 times higher than in women with fatty breasts. Screening mammography in women with dense breasts has reduced sensitivity. This article reviews and discusses the indications, the advantages, and disadvantages of the method and also the sources of error in the ABUS examination. Disadvantages regarding image acquisition are the inability to assess the axilla, the vascularization, and the elasticity of a lesion, while concerning the interpretation, the disadvantages are the artifacts due to poor positioning, lack of contact, motion or lesion related. Many disadvantages can be diminished by additional attention and training. On the other hand, like any imaging technique, ABUS has disadvantages and even some limitations. ABUS is a standardized examination with many advantages in both screening and diagnostic settings: it increases the detection rate of breast cancer, improves the workflow, and reduces the examination time. Furthermore, for this group of patients, mammography has a low sensitivity in detecting breast cancers, especially if it is not associated with architectural distortion or calcifications. Patients with dense breasts have an increased risk of developing breast cancer compared to patients with fatty breasts. Automated breast ultrasound (ABUS) is an ultrasound technique that tends to be increasingly used as a supplementary technique in the evaluation of patients with dense glandular breasts.
