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.
为评估高频超声检查作为结肠癌患者诊断性成像方法的价值，我们首先对37例经灌肠造影和/或结肠镜检查确诊为结肠癌的患者的超声图像进行了评估。结果，超声诊断可能结肠癌的标准为：（1）结肠壁局限性、不规则增厚，回声不均匀且低；（2）轮廓不规则；（3）实时扫描时肠管无明显蠕动或形态改变；（4）肠壁分层消失。在过去4年中，连续41例患者的检查结果符合我们的超声标准。其中37例（90%）经灌肠造影和/或结肠镜检查证实患有结肠癌。我们的研究表明，高频实时超声检查可能是诊断结肠癌的一种有用的成像技术。
