目的研究子宫内膜良恶性病变MR表现在病情诊断方面的意义。方法选择2013年7月~2015年12月期间在我院经临床病理证实的子宫内膜肿块患者43例作为临床研究对象,分别进行病理学检查和MR动态增强扫描,MR动态增强扫描结果记为观察组,病理学检查结果记为对照组,观察观察组的误诊率。结果对照组检出子宫内膜恶性肿瘤41例,子宫内膜息肉1例,子宫内膜下肌瘤1例,观察组检出子宫内膜恶性肿瘤39例,子宫内膜息肉3例,子宫内膜下肌瘤1例,有2例子宫内膜恶性肿瘤误诊为子宫内膜息肉,误诊率4.65%,敏感度92.3%,特异度83.3%,组间差异无统计学意义,P>0.05。结论子宫内膜良、恶性息肉样病变的MR表现能够用于良恶性诊断,误诊率在4.65%,在子宫肌瘤大规模筛查方面有很高的临床应用价值。
Objective To study the significance of MR in diagnosis of benign and malignant endometrial lesions. Methods Seventy-three patients with clinically and pathologically confirmed endometrial mass in our hospital from July 2013 to December 2015 were selected as the clinical study objects and pathologically examined and MR dynamic contrast-enhanced scans were performed respectively. The results of MR dynamic contrast-enhanced scanning were recorded as The observation group and the pathological examination result were recorded as the control group, and the rate of misdiagnosis in the observation group was observed. Results In the control group, 41 cases of endometrial malignancy, 1 case of endometrial polyps, 1 case of endometrial fibroids, 39 cases of endometrial malignancies, 3 cases of endometrial polyps, 3 cases of intrauterine 1 case of fibroids, 2 cases of endometrial malignancies misdiagnosed as endometrial polyps, the misdiagnosis rate was 4.65%, the sensitivity was 92.3% and the specificity was 83.3%. There was no significant difference between the two groups (P> 0.05). Conclusion MR imaging of benign and malignant endometrial lesions can be used for benign and malignant diagnosis with a misdiagnosis rate of 4.65%. It has a high clinical value in large-scale screening of uterine fibroids.
