A radiologic reporting system for computer-aided diagnosis with associated database. Hokkaido University Diagnostic...

Area of Science:

• Radiology and Medical Imaging
• Health Informatics
• Artificial Intelligence in Medicine

Background:

• Radiologists face challenges in efficiently reporting medical images and identifying potential diseases.
• Integrating diagnostic information into hospital systems (HIS) is crucial for patient care.

Purpose of the Study:

• To present the development and applicability of a novel reporting system for medical images.
• To evaluate the system's efficiency in report generation and diagnostic accuracy.
• To describe the database structure and data transfer capabilities to a Hospital Information System (HIS).

Main Methods:

• Development of a reporting system integrating diagnostic information management and disease probability calculation.
• Implementation of data conversion and transfer protocols to the HIS of Hokkaido University Hospital.
• Analysis of system performance over 5 years, processing approximately 20,000 reports.

Main Results:

• The system demonstrated proven applicability for Computed Tomography (CT) and ultrasonography.
• Efficient report production was achieved, with a defined database structure.
• The system's hit ratio for calculated diagnoses was evaluated.

Conclusions:

• The developed reporting system effectively assists radiologists in medical image interpretation and disease diagnosis.
• The system enhances efficiency and integrates seamlessly with existing hospital information infrastructure.
• The findings support the utility of such systems in improving diagnostic workflows and patient data management.
