MR结肠水成像的临床应用研究

目的 评价MR结肠水成像的临床应用价值.资料与方法 对50例患者进行结肠气钡双重造影和MR结肠水成像的对比研究.结果 结肠癌共36例,结肠气钡双重造影检查34例见病区肠壁僵硬、不规则,肠管扩张受限,2例病变显示欠佳;MR结肠水成像29例显示肠管的狭窄、肠壁僵硬,且病变范围显示更清晰.肠套叠3例,结肠气钡双重造影,均只显示部分套头及套鞘;MR结肠水成像均确切地显示了套入肠管的全貌.结肠癌合并肠套叠1例,结肠气钡双重造影仅显示部分套头及套鞘,癌肿病灶未显示;MR结肠水成像不仅使套入肠管全貌显示良好,而且使癌肿内坏死区良好显示.结肠息肉6例,溃疡性结肠炎4例,在结肠气钡双重造影中病变的大小、形态、数目均得以良好显示,但MR结肠水成像仅能使部分病变清晰显示.两者结果对比表明,MR结肠水成像对结肠癌、肠套叠等病变的显示更清晰、具体,更能确切地显示病变的实际大小和内部结构;两者在定性诊断上无显著性差异(定性诊断结果 经统计学分析,χ2=1.95,0.1＜P＜0.25),但MR结肠水成像对结肠多发性小病变的定量诊断不如结肠气钡双重造影.结论 MR结肠水成像对结肠癌、肠套叠等梗阻性病变的检查,比结肠气钡双重造影更具优越性,具有较高的临床使用价值,可作为结肠病变的辅助检查应用于临床.

The Clinical Application of MR Hydrography in Colon

Objective To evaluate the clinical value of MR hydrography in colon.Materials and Methods Air-barium double contrast colonography and MR hyrography of colon were performed in 50 patients.Results In 36 colon carcinoma,34 cases showed that intestinal walls of disease areas were stiff,irregular and distended limited with air barium double contrast colonography,2 cases were not very clearly depicted; 29 cases showed that intestines were stenosis,walls of intestines were stiff,and the range of lesion were more d...
