Prostate, Mass screnning, Ultrasound
Ultrasonic scan of the prostate with transrectal rotating transducer has played an important role in diagnosis of prostatic diseases especially for detecting prostatic carcinoma. Up-to-now ultrasound facilities specially used for urology have not been enough to meet the need of screening test on a large scale. For this reason, the authors make a joint appeal: Let us develop a new type of rectal probe (see appendix) which could be used to do sector scanning of the prostate transversely. Then the potential of popular type of ultrasound facilities—numerous real-time sector scanners will be brought into full play. The transrectal rotating transducer of some type of ultrasonic instrument for urology now have been used, could also be improved for raising its efficiency. We believe that the task of screening test for prostatic carcinoma will take on a new look when advanced transrectal scanning technique is widely used as much as possible. Appendix: From clinical point of view, a design of the transducer mentioned above has been proposed.
