    Area of Science:

    • Urology
    • Medical Imaging
    • Diagnostic Technology

    Background:

    • Transrectal ultrasonography (TRUS) is crucial for visualizing the prostate gland.
    • Accurate diagnosis of prostatic diseases relies on detailed imaging of anatomical structures and pathological changes.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of prostatic disease detection using pattern analysis of gray scale echograms in transrectal ultrasonography.
    • To classify ultrasonic findings into acoustical and pathological-anatomical patterns.

    Main Methods:

    • Classification of ultrasonic findings into acoustical patterns (solid, cystic, mixed).
    • Classification into pathological-anatomical patterns (internal gland, external gland, nodule, stone, miscellaneous).
    • Analysis of prostatic inside echoes using these pattern classifications.

    Main Results:

    • Improved gray scale echograms provided clear visualization of prostatic anatomical structure and pathological changes.
    • Diagnostic accuracy for prostatic diseases using pattern analysis reached 89%.
    • This represents a 9% improvement compared to conventional display methods.

    Conclusions:

    • Pattern analysis of prostatic echoes in TRUS significantly enhances diagnostic accuracy for prostatic diseases.
    • The classification system effectively categorizes ultrasonic findings, aiding in disease identification.
    • This advanced imaging technique offers improved diagnostic performance over conventional methods.
