[Color Doppler in the diagnosis of malignant prostatic neoplasia. Preliminary results].

In the field ultrasonic diagnosis the application of color code to the duplex Doppler signal is without doubt the most up-to-date method. The common knowledge according to which all heteroplastic structures need a large quantity of O2 and provoke the formation of new vessels with the angiogenesis factor, with particularly rapid, and tumultuous fluxes due to the presence of shunt, is the basis for the use of color doppler in research on neoplasia in the initial phase. The authors submitted 11 patients considered at risk, to an echocolor Doppler study of the prostate, with a transrectal biplane probe of MHz. The exclusive application of ultrasonography grey scale, permitted the diagnosis of malignant neoplasia in 5 of these subjects. The following "color" exploration led to a cancer diagnosis in 10 patients. A bioptic check carried out through transperineal way color guided allowed the diagnosis of 8 'adenocarcinomas' and 1 undifferentiated CA.
