Deep Learning Tool is Accurate in Detection and Quantification of Hemorrhage on Non-Contrast CT, According to Research

TUSTIN, Calif., June 7, 2018 – Peter Chang, MD, current neuroradiology fellow at UCSF and recently recruited co-director of the UCI Center for Artificial Intelligence in Diagnostic Medicine (CAIDM), is the honorary recipient of the Cornelius G. Dyke Memorial Award, given by the American Society of Neuroradiology (ASNR) for his work in developing a customized deep learning system with over 97% accuracy in near real-time detection of hemorrhage on non-contrast CT (NCCT) exam of the head. The research, which was sponsored by Canon Medical Systems USA, Inc., involved algorithm development on over 10,000 NCCT studies and included both detection and quantification of intraparenchymal, epidural/subdural, and subarachnoid hemorrhages. Co-investigator Daniel Chow, who will join Dr. Chang as co-director at the CAIDM, explains that a tool such as this “may be implemented either as a triage system to assist radiologists in identifying high-priority exams for interpretation and/or as a method for rapid quantification of ICH volume, overall expediting triage of patient care and offering more detailed information to guide clinical decision making.”

“I am deeply honored to receive this prestigious award from the American Society of Neuroradiology,” said Peter Chang, MD. “I appreciate the support of my research team and those involved in helping advance the research of convolutional neural networks for medical image recognition.”

“Peter Chang’s research endeavor in the field of deep learning convolutional neural networks is extraordinary,” said Dominic Smith, senior director, CT, PET/CT, and MR Business Units, Canon Medical Systems USA, Inc. “His research is an important milestone in better understanding the tremendous potential for deep learning tools to improve patient care – an area we are deeply committed to.”

The award, presented at ASNR’s 56th Annual Meeting, was established to honor Cornelius G. Dyke, one of the pioneers in neuroradiology, and is given to an assistant professor, fellow or resident for excellence as demonstrated in a paper, which represents original, unpublished research in some aspect of neuroradiology. The award entails an honorarium and invitation to present the work at the 56th Annual Meeting in 2018.
