THE THREE-DIMENSIONAL ULTRASOUND IMAGING OF THE PROSTATE
The purpose of the study was to evaluate the efficiency of identifying the volume of the prostate by using the threedimensional sonography compared with the identification of the derivatives of the prostatic specific antigen. In the study there was a good agreement between sonographic volumes of the prostate with real volumes, especially in the study of adenomas and cancers. Measurement accuracy of volumes is extremely high, especially in the study of adenomas with a clear distinction between the transition zone and the intact part of the prostate gland. In further studies it is necessary clearly define the importance of measuring the volume, but we believe that the three-dimensional sonography, being accurate and reproducible diagnostic method, especially for the measurement of volume, can be a routine study in qualitative and quantitative assessment of the pathology of the prostate gland.
