BIRADS Classification in Breast Tomosynthesis Compared to Mammography and Ultrasonography

چکیده
This paper presents the Malmö Breast Tomosynthesis project. The tomosynthesis equipment is described as well as the patient selection and image acquisition. Special focus is given to one of the studies of the project, which is a comparison of the diagnostic performance between breast tomosynthesis (BT), digital mammography (DM) and ultrasonography (US): Tumor classification according to the BIRADS system was performed on 40 cancers imaged with DM, US and BT. The patients were selected on the basis of subtle signs of breast cancer on DM or negative findings on DM but suspicious lesions on US. The BIRADS scores based on the BT images were significantly higher than 1view DM and 2-view DM, and equal to 2-view plus US. The results suggest that BT may be a suitable technique for breast cancer screening.

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

متن کاملBIRADS classification in mammography.
The Breast Imaging Report and Data System (BIRADS) of the American College of Radiology (ACR) is today largely used in most of the countries where breast cancer screening is implemented. It is a tool defined to reduce variability between radiologists when creating the reports in mammography, ultrasonography or MRI. Some changes in the last version of the BIRADStrade mark have been included to r...
متن کاملThe Principles of Contrast Mammography
Multiple clinical studies have demonstrated that the use of screening mammography reduces mortality from breast cancer. 2, 3 The efficacy of mammography depends upon the ability to identify cancers based on the differing absorption of x-rays in cancerous tissue compared to adipose and glandular tissue. In mammography cancers often appear ‘white’, similar to normal glandular tissue, making cance...
