Artifical intelligence: Impact on mammogram interpretation 02 Nov 2017

Deep learning, a form of machine learning, has recently received a substantial amount of attention in the radiologic community. This talk will briefly review the basics of machine learning and (deep) artificial neural networks.
It will then bridge to the latest clinical research from their group: to estimate the ability of current state-of-the-art algorithms, a head-to-head comparison of the cancer detection rate of radiologists versus a generic deep learning image analysis software was performed. The overall performance was comparable, whereas the software exhibited consistently higher sensitivity but lower specificity [1].
Lastly, the limitations of machine learning and the opportunities for radiology in the near future will be discussed.
Educational aims:
• To understand the basic concepts behind machine learning and deep neural networks
• To understand the limitations of those methods
• To summarise the current state of machine learning research in breast imaging

Anton Becker

Dr Anton Becker Research Fellow, University Hospital of Zurich Dr Anton Becker holds a medical degree from the University of Zurich. He initially developed an interest in artificial neural networks while working on his Master’s thesis in neuroanatomy under the supervision of Professor H.P. Lipp and Dr I Amrein in 2009. After starting his training in diagnostic and interventional radiology at the University Hospital of Zurich, he completed a research fellowship with Professor Andreas Boss focusing on MRI and machine learning. He has a strong interest in functional, metabolic and oncological imaging as well as machine learning applications in radiology.
