Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

Health Informatics
Clinical Terminology
Medical Information Systems

Background:

SNOMED CT (Systematized Nomenclature of Medicine - Clinical Terms) is a comprehensive clinical terminology.
Post-coordination allows users to create new concepts by combining existing ones, offering flexibility but posing implementation challenges.
Previous research and implementation projects highlight issues with user-directed concept coordination.

Purpose of the Study:

To analyze scenarios of user-directed post-coordination in SNOMED CT.
To identify usability and representation problems associated with SNOMED CT post-coordination.
To provide recommendations for improving SNOMED CT post-coordination in clinical practice.

Main Methods:

Analysis of SNOMED CT documentation regarding user-directed concept coordination scenarios.
Leveraging experiences from national mapping projects and data collection investigations.
Evaluation of identified scenarios for usability and representation issues.

Main Results:

Identified significant usability and representation problems in SNOMED CT post-coordination.
Observed issues include a high number of relationships for refinement, improper refinement options, and incorrect formal definitions.
Lack of support for applying editorial rules was also noted as a key problem.

Conclusions:

Effective SNOMED CT post-coordination requires enhanced sanctioning mechanisms.
Increased consistency in the formal definitions of SNOMED CT concepts is crucial.
Real-time analysis of post-coordinated expressions is necessary for practical implementation and improved usability.
