    This study introduces a computer-based image analysis system to detect subtle bone changes in conditions like rheumatoid arthritis and osteoarthritis. The software reliably quanties early morphological alterations, outperforming visual inspection of radiographs.

    Area of Science:

    • Orthopedics
    • Medical Imaging
    • Computational Biology

    Background:

    • Early detection of bone morphology changes in rheumatoid arthritis and osteoarthritis is challenging with conventional radiography.
    • Visual assessment of radiographs has limitations in quantifying subtle periarticular bone alterations.

    Purpose of the Study:

    • To describe the software operations of a novel computer-based image analysis system.
    • To demonstrate the system's capability in detecting small changes in periarticular bone contours.

    Main Methods:

    • Development and detailed description of a computer-based image analysis software.
    • Application of the software to analyze periarticular bone contours from radiographs.

    Main Results:
