Purpose: The reliability and objectivity of computer assisted transrec
tal ultrasound are examined. Materials and Methods: Pathological exami
nation of radical prostatectomy specimens was compared prospectively t
o automated cancer detection in corresponding transrectal ultrasound i
mages. Results: For automated cancer detection, a sensitivity of 0.75
and a specificity of 0.78 were obtained. Moreover, 74% of human interp
retation of the percentage of malignancy in the analyzed images was eq
ual to the actual calculated percentage (Pearson's product moment corr
elation coefficient 0.85). Conclusions: Comparing these results to tho
se obtained with normal transrectal ultrasound, automated analysis pro
vides additional information in the interpretation of transrectal ultr
asound images by color coding them in an objective manner according to
the probability of malignancy.
