The value of examining blood supply in prostate cancer using Doppler frequency analysis.
Stating the contribution of Doppler ultrasound examination (DU) of prostatic vascularisation towards timely diagnosing prostate cancer. 87 patients with bioptically proven prostate cancer and 10 healthy young men of control group were examined by transrectal ultrasound in B mode, colour flow mapping (CFM) and Doppler frequency analysis. (DFA) The distribution of vessels in prostate is not specific for carcinoma and using CFM, it is impossible to distinguish normal tissue from carcinoma. DU combined with other methods as rectal palpation, PSA, transrectal sonography in B mode may, however, increase carcinoma suspicion, and quicken the indication of considered bioptic puncture.
