ECR 2016 Book of Abstracts - D - Satellite Symposia

D Satellite Symposia ECR/ESR takes no responsibility for the content of the Satellite Symposia, and the opinions expressed therein do not necessarily reflect those of ECR/ESR Automated 3D breast ultrasound is a new technique, which scans the breast automatically and almost entirely. Data sets can be stored and are available for 3D cross correlating review. This new technique eliminates significantly the subjectiv-ity of conventional ultrasound, disconnects US data acquisition and assessment, facilitates the possibility of double reading, presurgical workup planning, review of follow-up studies and the application of computer aided detection. Automated 3D ultrasound can be implemented in the clinical radiological setting and possibly in a personalized screening program for breast cancer. Learning Objectives: 1. To become familiar with the 3D breast ultrasound technique and scanning protocols. 2. To comprehend the indications and limitations of 3D breast ultrasound. 3. To become familiar with the diagnostic accuracy of 3D breast ultrasound and to appreciate the potential added value for breast cancer screening. 4. To highlight novel developments in 3D breast US, such as computer aided detection. Potential role of digital breast tomosynthesis (DBT) in breast cancer diagnosis N. Uchiyama; Tokyo/JP In this lecture, the author addresses the potential role of DBT in comparison with other diagnostic modalities in breast cancer including technical principles and clinical experiences. In comparison with 2D mammograms, DBT is better able to distinguish a lesion from overlapping breast tissue and to improve detection performance especially of masses and makes it possible to clarify the location or distribution of microcalcifications. In comparison with CE MRI, the diagnostic performance of DBT is comparable or better in some cases. CE MRI has an advantage in detecting cancerous lesions and extensive intraductal component or daughter lesions associated with the main cancerous lesions. However, by CE MRI, the differentiation between a small cancerous or benign lesion is sometimes difficult. On the other hand, the pixel size of DBT is much smaller than MRI and has an advantage regarding the morphological diagnostic approach. In comparison with US, the diagnostic performance of DBT is comparable in detecting mass lesions. In addition, DBT has advantages in detecting the lesions with microcalcifications, a large area, or multi-focal lesions in comparison with US. Learning Objectives: 1. To understand image acquisition and image reconstruction principles of DBT 2. To understand the advantages and disadvantages of DBT compared to other diagnostic modalities 3. To understand the findings of DBT …
