Abstract
Improved gray scale echograms in transrectal ultrasonography clearly can visualize the anatomical structure of and pathological changes in the [human] prostatic gland. This study includes the classification of ultrasonic findings from the prostatic gland into acoustical pattern groups (solid, cystic and mixed) and pathological-anatomical pattern groups (internal gland, external gland, nodule, stone and miscellaneous). The diagnostic accuracy of prostatic diseases using pattern analysis of prostatic inside echoes was 89%, a 9% improvement over that provided by conventional display.
