目的:探讨磁共振动态增强扫描在卵巢肿瘤诊断中的应用价值.方法:研究对象为2020年10月~2021年10月本院收治的80例卵巢肿瘤患者,均接受磁共振动态增强扫描检查,以手术病理检查结果为金标准,分析磁共振动态增强扫描的诊断效能.同时将良恶性肿瘤的强化均匀度、时间-信号强度曲线类型、第一分钟强化率、强化峰值时间进行对比,分析磁共振动态增强扫描的良恶性鉴别价值.结果:手术病理检查结果显示80例患者中44例为良性肿瘤,36例为恶性肿瘤,磁共振动态增强扫描结果显示42例为良性肿瘤,34例为恶性肿瘤,误诊2例,确诊率为95.00%(76/80).44例良性肿瘤中34例均匀强化,10例不均匀强化;36例恶性肿瘤中,6例均匀强化,30例不均匀强化.良恶性肿瘤的曲线类型、第一分钟强化率、峰值时间特点差异显著(P<0.05).恶性肿瘤的微血管计数明显高于良性肿瘤(P<0.05).结论:磁共振动态增强扫描在卵巢肿瘤诊断中具有极高的应用价值,同时有助于良恶性肿瘤的鉴别诊断.
The Value of Dynamic Contrast-Enhanced Magnetic Resonance Scan in the Diagnosis of Ovarian Tumors
Objective:To investigate the value of dynamic contrast-enhanced magnetic resonance scan in the diagnosis of ovarian tumors.Methods:The subjects were 80 patients with ovarian tumors admitted to our hospital from October 2020 to October 2021.All of them received dynamic enhanced MR scanning.The diagnostic efficacy of dynamic enhanced MR scanning was analyzed based on the results of surgical and pathological examinations.At the same time,the enhancement uniformity,time signal intensity curve type,enhancement rate at the first minute,and enhancement peak time of benign and malignant tumors were compared to analyze the differential value of dynamic enhanced MR scanning in benign and malignant tumors.Results:The results of surgical pathology showed that 44 of 80 patients were benign tumors,36 were malignant tumors.The results of dynamic contrast-enhanced magnetic resonance scan showed that 42 patients were benign tumors,34 patients were malignant tumors,2 patients were misdiagnosed,and the diagnostic rate was 95.00%(76/80).34 of 44 benign tumors had homogeneous enhancement and 10 had heterogeneous enhancement;In 36 cases of malignant tumors,6 cases had homogeneous enhancement and 30 cases had heterogeneous enhancement.There were significant differences in curve type,enhancement rate at the first minute and peak time between benign and malignant tumors(P<0.05).The microvessel count of malignant tumors was significantly higher than that of benign tumors(P<0.05).Conclusion:Dynamic contrast-enhanced magnetic resonance scan is of great value in the diagnosis of ovarian tumors,and is helpful in the differential diagnosis of benign and malignant tumors.
