[Sonographic assessment of tumor spread in rectal cancer].

The authors present the combined method of sonographic assessment of rectal carcinomas in respect of spread of tumour as well as metastasising, using linear rectal sounds (Aloka-Hellige) and rotating rectal sounds (Brüel-Kjear). This method involves further diagnostic progress compared with the methods employed to date. The article comprises application in 24 patients with histologically confirmed carcinoma of the rectum.
