title: Transrectal ultrasound imaging of the prostate: review and perspectives of recent developments.
abstract: We present a critical review of the recent literature and discuss the development and prospective view of the evaluations of transrectal ultrasound with regard to prostate malignancy. We illustrate this with personal experiences. Material and Methods: Based on a critical evaluation of clinical data we address the apparent shortcoming of greyscale transrectal ultrasonography in the assessment of prostate cancer. New developments and future possibilities are also discussed. Evaluation of the value of greyscale transrectal ultrasonography in the diagnosis of prostate cancer indicates a limited role, because of the non-uniform appearance of prostate cancer on the ultrasound images. Ameliorating of transrectal ultrasound, like the use of contrast ultrasonography, could improve the detection of prostate cancer. Although the use of greyscale transrectal ultrasonography lacks sensitivity and specificity for the diagnosis of prostate cancer, its use in volume measurement of the prostate and biopsy guidance is unquestionable. The first results of the application of contrast ultrasonography are promising, both in detection of prostate cancer as in treatment follow up. Other developments like improvement of transducer and computer technology could make the use of ultrasound more versatile. However, future research will indicate whether all these improvements will lead to clinical applications.
