"Diagnostic Performance of an Artificial Intelligence System in Breast Ultrasound"

A paper co-authored by PhD student Jhiye Baek and Professor Kevin Parker titled "Diagnostic performance of an artificial intelligence system in breast ultrasound" has been published in the Journal of Ultrasound in Medicine. The paper describes the results of a study of the performance of an artificial intelligence program designed to assist radiologists in the diagnosis of breast cancer, relative to measures obtained from conventional readings by radiologists. Co-authors include Avice O'Connell of the URMC Department of Imaging Sciences and collaborators at the Duke School of Medicine in Durham, NC (Sin-Ho Jung), the University Hospital in Palermo, Italy (Tommaso Bartolotta), and the Fondazione Istituto G. Giglio Hospital in Cefalù, Italy (Alessia Orlando). The abstract follows; more information can be found here.

Abstract: Objectives: We study the performance of an artificial intelligence (AI) program designed to assist radiologists in the diagnosis of breast cancer, relative to measures obtained from conventional readings by radiologists. Methods: A total of 10 radiologists read a curated, anonymized group of 299 breast ultrasound images that contained at least one suspicious lesion and for which a final diagnosis was independently determined. Separately, the AI program was initialized by a lead radiologist and the computed results compared against those of the radiologists. Results: The AI program's diagnoses of breast lesions had concordance with the 10 radiologists' readings across a number of BI-RADS descriptors. The sensitivity, specificity, and accuracy of the AI program's diagnosis of benign versus malignant was above 0.8, in agreement with the highest performing radiologists and commensurate with recent studies. Conclusion: The trained AI program can contribute to accuracy of breast cancer diagnoses with ultrasound.
