Summary
A novel radiology reporting system uses a hierarchical structure and keywords to improve data organization. This system demonstrates high accuracy in capturing key findings, enhancing radiological information passage and database formation.
Area of Science:
- Radiology Informatics
- Medical Imaging Analysis
- Health Information Systems
Context:
- Current radiology reporting relies on free-text descriptions, posing challenges for data retrieval and analysis.
- The need for structured reporting in radiology is crucial for improving diagnostic accuracy and building comprehensive databases.
- The Open System Interconnection (OSI) model provides a framework for structured data management.
Purpose:
- To propose and evaluate a new radiology reporting system utilizing a hierarchical structure.
- To assess the feasibility and utility of an intermediate language for keyword extraction in radiological reports.
- To improve the passage and formation of radiological information through structured data management.
Summary:
- A hierarchical radiology reporting system was developed, generating an intermediate language file of semantically linked keywords.
- The system integrates this intermediate language with free-text descriptions, mirroring the OSI model's structure.
- Testing on 57 echography reports showed a 97.4% keyword hit ratio and an 88.7% hit case ratio, demonstrating high accuracy.
Impact:
- The proposed system is feasible and useful for enhancing radiological information passage and creating radiology databases.
- Successful implementation requires strict standardization of descriptive words and findings criteria for practical application.
- This approach offers a pathway toward more efficient and structured radiological data management.
