ACRCommon is a collection of common radiology terms and semantic structures that facilitates interaction with ACR products and services. ACRCommon leverages existing ontologies and coding schemes such as RadLex, and CPT and is organized around the fundamental and derived axes of scenarios, procedures, and findings. Most importantly, ACRCommon is based on ACR’s experiences and challenges interacting with facilities to deliver and consume content (e.g. registries, guidelines) and participate in key programs (e.g. ACRSelect, Accreditation).
