[Color doppler mapping in the diagnosis of prostatic carcinoma]

The authors examined 70 patients with histologically confirmed prostate carcinoma in different stages by transrectal ultrasonography in the B mode and by ultrasonography by colour flow mapping and pulsed Doppler. They investigated the distribution of the blood supply, resistance index (RI) and pulsatility index (PI). It did not prove possible to find an association between the blood supply and stage T nor with grading G. A certain relationship was observed between the blood supply and the progression of the tumour. In newly detected growing tumours and in progressing tumours not responding to treatment the blood supply was more ample. On the other hand, in all stationary tumours reacting well to treatment the blood supply was reduced.
