SIIM and HIMSS recommend SNOMED CT as the standard anatomy terminology for imaging

20 Jun 2025

SNOMED International is pleased to announce that the Society for Imaging Informatics in Medicine (SIIM) and the Healthcare Information and Management System Society (HIMSS), following years of research and review of a number of existing ontologies, are recommending SNOMED CT to their members as the standard anatomy terminology for imaging.


The Healthcare Information and Management Systems Society (HIMSS) - Society for Imaging Informatics in Medicine (SIIM) Enterprise Imaging Community (HSEIC) identified anatomy as a crucial data element necessary to facilitate the consumption and interoperability of medical imaging data in 2019. The first paper, The Importance of Body Part Labeling to Enable Enterprise Imaging: A HIMSS-SIIM Enterprise Imaging Community Collaborative White Paper, was published in 2021. The HIMSS-SIIM Enterprise Imaging Community Data Standards Evaluation Workgroup conducted a comprehensive assessment of anatomical ontologies with the aim of facilitating enterprise imaging. They analyzed different ontologies and assessed their suitability for the complex landscape of enterprise imaging. Importantly, the workgroup incorporated feedback from providers across different medical and surgical specialties, imaging technology experts, and vendors to identify key features of the ideal ontology and create real-world clinical use cases.


The result of the evaluation work is the whitepaper, "Report of the HIMSS-SIIM Enterprise Imaging Community Data Standards Evaluation Workgroup: Anatomic Ontology Assessment," published in June 2024. SNOMED CT received the highest possible marks for almost every criterion and use-case workflow step.. Additionally, the fact that it offers multiple resources and open-source tools to assist the developer community were cited as additional reasons to recommend SNOMED CT for the imaging community. The assessment ultimately concludes that SNOMED CT is the most viable solution for standardizing anatomy terminology across the medical imaging community.


SNOMED International Senior Terminologist Yongsheng Gao, PhD, attended a recent SIIM conference, where he and Dawn Cram, CIIP, Chair of the workgroup, presented on adopting SNOMED CT for anatomy nomenclature in enterprise imaging. “The comprehensive coverage of SNOMED CT and clinically meaningful representation of relationships of body parts meet different requirements from wide medical imaging specialties,” says Dr. Gao. Ms. Cram discussed the assessment of the existing ontologies and recommended that the enterprise imaging industry focus its efforts on the adoption and implementation of SNOMED CT and establish a relationship between the HSEIC and SNOMED International to enable the community's participation.


SNOMED International CEO Don Sweete welcomed the decision. “Millions of patients undergo various types of imaging, from X-rays to MRIs to CT scans, daily. In fact, according to the International Atomic Energy Agency, over 4 billion diagnostic radiological and nuclear medicine procedures are performed globally each year, and without the use of standardized terminology, the risk for harm to those patients increases substantially, so we salute the HSEIC decision to recommend SNOMED CT to their members.”
