The improved gray scale echography in transrectal ultrasonotomography can provide fine visualiza-tion of anatomical structures and pathological changes of prostatic gland. Ultrasonic findings from the inside of the prostate were classified into three acoustical patterns : solid pattern, cystic pattern and mixed pattern. The findings under each pattern were sub-classified according to their shape, distribution and border. Another classification was also done from patho-anatomical view dividing the findings into inner gland pattern, outer gland pattern, nodule pattern, stone pattern and miscellaneous. Each pattern was statisucally, ecaluated in normal and abnormal evaluated in normal and abnormal stone pattern and miscellaneous. Diagnostic criteria for prostatic diseases were revised, considering the internal echo patterns from the prostate. Diagnostic accuracy in 167 gray scale prostatic scans was 89 per cent, 9 per cent higher as compared with that of conventional scan. Gray scale transrectal ultrasonotomography proved to be more accurate diagnostic means for analysis of prostatic pathology.
