76 patients underwent ultrasound guided prostatic biopsy performed using cutting needle for the suspicion of prostatic neoplasm. All the patients preliminary underwent color-Doppler examination of the suspicious nodules already diagnosed by B-mode ultrasonography. 64 prostatic neoplasms (84%) were histologically diagnosed. Only 40 out of them had a significant signal at color-Doppler with a sensitivity of 62% which is lower than other reported studies on literature. Specificity, on the contrary was about 91%. There was a low direct correlation between the grading of the neoplasm and the color flow mapping while anyone was revealed between tumour size and color signal. Only in one case color-Doppler examination revealed a suspicions area not seen on B-mode ultrasonography; it resulted to be a cancer by means histology. The use of color-Doppler has net significantly prolonged the lenght of standard examination. Color-Doppler shows to be quite useful in the diagnosis of prostatic neoplasm but it cannot be easily considered for clinical practice till now.
