目的 研究增强CT用于临床诊断 腹部肿瘤腹腔转移的价值。方法 于2014 年1月-2015年4月期间选取我院影像科CT 室接诊的腹部肿瘤转移患者60例。按诊 断方法不同分为观察组(增强CT扫描)和 对照组(常规CT扫描)，以手术病理检查 结果为准，对比两组诊断正确率、最小 种植灶面积、不良反应发生率。结果 观 察组诊断正确率为93.33%，较对照组的 (83.33%)高，P＜0.05；观察组诊断出最 小种植灶为(1.00×0.70)mm2 ，较对照组 的(2.72×1.80)mm2 小，观察组种植灶平 均宽度、长度均小于对照组，P＜0.05； 观察组不良反应发生率(3.33%)与对照组 (0.00%)比较差异不显著，P＞0.05。结论 增强CT用于临床诊断腹部肿瘤腹腔转移有 以下优势：对小种植灶具更高敏感性，显 著提高诊断准确率；不良反应发生率低， 安全性高。

Objective This paper is to look into the value of enhanced CT for clinical diagnosis of peritoneal metastasis of abdominal tumor. Methods Sixty patients with abdominal tumor metastasis admitted in CT Room, Division of Image of the Hospital from January, 2014 to April, 2015 were selected, and these patients were divided into two groups according to different diagnostic methods (enhanced CT scan) and the control group (conventional CT scan), surgical pathology results were referred, and the diagnostic accuracy, the area of minimum planted lesion and incidence of adverse reactions of two groups of patients were compared. Results The diagnostic accuracy of patients in the observation group was 93.33%, being higher than that of patients in the control group (83.33%)(P<0.05). Minimum area of planting lesions of patients in the observation group hit (1.00×0.70) mm2 , being lower than that of patients in he control group at (2.72×1.80) mm2 , average width and length of planting lesions of patients in the observation group were less than those of patients in the control group (P<0.05). There comparison difference in the incidence of adverse reactions on patients in the observation group (3.33%) and that on patients in the control group (0.00%) was not significant, P>0.05. Conclusions Enhanced CT delivers the following advantages in clinical diagnosis of abdominal peritoneal metastasis tumor: Higher sensitivity is imposed on small-size planting lesions, significantly improving the diagnostic accuracy. Enhanced CT is provided with low incidence of adverse reactions and high safety.
