目的研究CT与增强CT在诊断腹 部肿瘤腹腔转移中的临床价值，以提高对 该疾病的诊断水平。方法 以我院收治的 86例经病理证实为腹部肿瘤腹腔转移患者 为研究对象，将其根据诊断方式不同分为 对照组与观察组，对照组行CT诊断，观察 组采用增强CT诊断，对比病理诊断结果， 比较两种诊断方式的诊断准确率。结果 观察组诊断准确率为93.0%，明显高于对 照组的58.1%，P＜0.05；观察组检出最小 种植灶为(1.0±0.9)cm2 ，明显优于对照 组的(2.6±1.8)cm2 ，P＜0.05，差异具有 统计学意义。结论 与CT相比，增强CT在 诊断腹部肿瘤腹腔转移方面具有较高的临 床价值，其定位性更加准确，可以提供更 多的信息，尤其是对小种植病灶的诊断率 更高，值得在临床实践中广泛应用。

Objective This paper is to anlysis clinical value of CT and enhanced CT in the diagnosis of peritoneal metastasis of abdominal tumor in order to improve the diagnosis level on diseases. Methods Eighty six patients admitted by the Hospital pathologically confirmed to suffer from peritoneal metastasis of abdominal tumor were selected as research subjects, who were divided into the control group and the observation group according to diagnostic methods, patients in the control group underwent CT diagnosis, and patients in the observation group underwent enhanced CT diagnosis, results of pathological diagnosis and diagnostic accuracy rates of two diagnosis way were compared. Results Diagnostic accuracy on patients in the observation group hit 93.0%, being significantly higher than that on patients in the control group at 58.1% (P<0.05). Detected minimum planted lesions hit (1.0-0.9) cm squared, significantly better than that of control group (1.0±0.9) cm2 (P<0.05), the differences were statistically significant. Conclusion Enhanced CT delivers high clinical value in the diagnosis of abdominal peritoneal tumor metastases when compared to that of CT, its location is more accurate, more information can be provided, especially it delivers more diagnostic rate on minor planted lesions, being worthy of wide application in clinical practices.
