ABSTRACT
Three-dimensional automated breast ultrasonography (ABUS) has been approved the purpose of screening studies, as an adjunct to mammography. ABUS provides proper orientation and documentation, resulting in better reproducibility. Optimal image quality is essential for proper diagnosis, and good image quality should be guaranteed in the use of ABUS in clinical settings. Image quality in ABUS highly depends on the factors surrounding the acquisition procedure. Artifacts can interfere with the visibility of abnormalities, reduce overall image quality, and introduce clinical and technical problems. Nipple shadow and reverberation artifacts are some of the artifacts frequently encountered in ABUS. Radiologists should be familiar with proper image acquisition techniques and the artifacts in order to acquire quality images.
