To assess the value of high‐frequency ultrasonography as a diagnostic imaging procedure in patients with colon carcinoma, we first evaluated the sonograms of 37 patients who had been already diagnosed with contrast enema and/or colonoscopy as having colon carcinoma. As a result, the sonographic criteria for diagnosis of a possible colon carcinoma were (1) a localized and irregular thickening of the colonic wall with heterogenous low echogenicity, (2) an irregular contour, (3) a lack of demonstrable movement or change of configuration of the bowel on real‐time scanning, and (4) absence of wall stratification. During the last 4 years, 41 consecutive patients had findings meeting our sonographic criteria. In 37 patients (90%), the presence of colon carcinoma was confirmed by contrast enema and/or colonoscopy. Our study suggests that high‐frequency real‐time ultrasonography may be a useful imaging technique in diagnosis of colon carcinoma. © 1994 John Wiley & Sons, Inc.
