目的：探究卵巢肿瘤MRI诊断的价值和方法。方法随机选取2014年1月~2015年6月在我院经手术和病理证实的40例卵巢肿瘤患者的MRI资料,并与病理结果相对比。结果在术前经MRI扫描诊断,40例患者中良性肿瘤为23例,恶性肿瘤为17例；手术后的诊断结果和术前的MRI结果一致。 MRI对卵巢肿瘤的诊断较为准确、合理。结论 MRI诊断技术可以明确的观察出肿瘤的大小、形态、良恶性等,具有较强的分辨率,应用价值比较高。“,”Objective To explore the value and method of MRI in the diagnosis of ovarian tumor.Methods The MRI datas of 40 cases of ovarian tumor confirmed by surgery and pathology which are selected randomly in our hospital during January 2014 and June 2015,compare with pathological results.Results MRI scan was used in 40 patients before operation including 23 cases of benign tumor and 17 cases of malignant tumor,the pathological results were consistent with the results of MRI.MRI diagnosis of ovarian tumors is accurate and reasonable.Conclusion MRI diagnosis technology can clearly observe the size,shape,benign and malignance of ovarian tumor,and has a strong resolution,the application value is relatively high.
