The RSNA Reporting Committee has created a library of radiology report templates submitted by expert panels, organizations, and individuals. Our goal was to integrate the RSNA RadLex® and structured reporting more fully in order to improve consistency and overcome barriers to the use of clinical imaging information in clinical, translational, and comparative-effectiveness research. Incorporation of the RadLex® ontology into reporting templates will enable the goal of semantic interoperability. Additionally, the structured reports serve the purpose of capturing the current language and terminology favored by practicing radiologists. Thus, a focused goal has been mapping the terms from the structured reports to RadLex®. Through this process, gaps in RadLex® have been identified and filled, while concurrent efforts in other realms have also boosted the RadLex® content.

An online library of the RSNA report templates has been created at radreport.org. The terms in the library’s reporting templates have been parsed and mapped to RadLex® using a semi-automated program termed RadMap. We tallied the occurrence of exact and partial matches to RadLex® and the frequency of post-coordinated terms. A gap analysis has been performed in order to identify reporting elements with no corresponding entity in the RadLex® ontology. This is a dynamic process as new report templates are added to the RSNA report template library.

Currently there are 130 English-language templates in the library containing 9,216 terms or phrases, corresponding to 3,208 unique terms. In 6,257 instances the terms have been mapped as exact matches to RadLex® terms and in 1,371 instances the matches are deemed partial matches, while 1,588 reporting terms are unmatched to RadLex®. The frequency of post-coordinated terms is 13%. Now 82% of terms are either exactly or partially matched to terms in RadLex®, compared to 67% one year prior.

The RSNA structured reporting templates serve as an important source of content development and validation for RadLex®.

The integration of RSNA structured reporting and RadLex® improves both efforts and creates a platform for imaging information use in QA/QI, translational, and comparative-effectiveness research.
