[Possibilities of CT and US in the diagnosis of colonic cancer].
The data of examination of 59 patients with colonic cancer were used to consider the potentialities of transabdominal, transrectal ultrasonography and X-ray computed tomography and to assess their value in diagnosing colonic cancer, including its "minor" forms. The paper describes the ultrasound and computed tomographic semiotics of colonic cancer and determines a place of the above techniques in the algorithm of radiation and instrumental studies. Inclusion of these techniques into the diagnostic algorithm may solve a range of differentially diagnostic problems and allows a preliminary analysis to be made in a tumor lesion according to the International TNM classification. Ultrasonography and X-ray computed tomography should be included into a range of basic methods for diagnosis of colonic cancer.
