Combining Human Expertise with Artificial Intelligence: Experimental Evidence from Radiology

We are grateful to Stanford University Hospital for facilitating data access. The authors acknowledge support from the Alfred P. Sloan Foundation (2022-17182), JPAL Healthcare Delivery Initiative, and MIT SHASS. The experiment was pre-registered on the AEA registry, number AEARCTR-0009620. The preanalysis plans are available at SSR Registration 9620 and SSR registration 8799. The project benefitted from collaboration with several radiologists, including Drs. Matthew Lungren, Curtis Langlotz, and Anuj Pareek of Stanford, Drs. Etan Dayan and Adam Jacobi of Mt. Sinai Hospital, Steven Truong of VinBrain and several radiologists at VINMEC, and teleradiologists at USARAD, Vesta Teleradiology, and Advanced Telemed.
