Session in Memory of Tao Wu, PhD: Wide Vs Narrow: The Decade Long Unsettled Debate on DBT Acquisition Angle
Description
Though digital breast tomosynthesis has been standard of care for over 15 years, the image acquisition parameters, especially the acquisition angles, encompass a wide range of variations. A question that warrants further investigation is the image quality trade-off between wide-angle and narrow-angle DBT acquisitions. In the past, wide-angle acquisitions suffer from long acquisition time; however, with clinical implementation of flying-focal spots, vendors can now achieve wide-angle acquisitions in clinically acceptable acquisition times. Never has the debate between wide-angle and narrow-angle DBT been more relevant. In this session, we wish to explore the physics of DBT acquisition parameters and their impact on image quality, present the current state of research on the topic, and invite a radiologist to give their opinion on the clinical impact of wide vs narrow angle DBT. This proposed session will consist of two speakers: 1) a physicists to speak on the physics of DBT acquisition parameters and their effect on image quality as well as recapping the current state of research on the topic, 2) a radiologist who will speak to the clinical impact of DBT acquisition parameters and discuss things of note from reading mammography exams from both narrow and wide angle systems. Both Stony Brook and MD Anderson are doing internal reviews of Siemens B.brilliant compared to Hologic’s narrow-angle system. Recruiting a radiologist from either institution would be ideal. Cleveland Clinic radiologists also read from both Hologic and Siemens systems.
