The American College of Radiology (ACR) and the College of American Pathologists (CAP) are collaborating on a joint project that will link radiology and pathology results and make them easily accessible for cancer tumor boards, Artificial Intelligence (AI), education, and research. The two organizations are creating a standards-based interface for the exchange of concordance data. The two groups have already engaged with Standards Development Organizations (SDOs) in developing and testing standards (IHE SDC and FHIR) for transmitting this information. ACR and CAP formed different committees for PI-RADS and BI-RADS and identified the Data elements for concordance from the CAP electronic Cancer Checklists. They developed a reference implementation of the infrastructure and conducted a demonstration and connectathon at SIIM 2022
