摘要

目的:探讨动态增强磁共振检查(DCE-MRI)在鉴别良恶性卵巢肿瘤中的应用价值,并分析相关参数.方法:选取2017年8月—2023年11月兴义市人民医院收治的89例卵巢肿瘤患者,均行MRI平扫、DCE-MRI检查,并以手术病理为金标准,统计良恶性检出情况及诊断效能,并用Kappa检验分析不同方法鉴别诊断与金标准的一致性;比较良恶性患者最大上升斜率(MSI)、平均强化时间(MET)、最大下降斜率(MSD)、达峰时间(TTP)差异.结果:89例患者经手术病理确诊恶性46例,其中MRI平扫检出42例恶性,DCE-MRI检出45例恶性.Kappa检验显示,MRI平扫鉴别诊断与金标准Kappa值=0.731,一致性尚可;DCE-MRI鉴别诊断与金标准Kappa值=0.933,一致性良好;DCE-MRI鉴别诊断灵敏度、准确率高于MRI平扫(P＜0.05);恶性患者MSI、MSD高于良恶性患者,MET、TTP短于良性患者(P＜0.05).结论:DCE-MRI在良恶性卵巢肿瘤鉴别中价值高,可准确分辨良恶性,便于早期精准治疗开展,更好改善患者预后.

Abstract

Objective To investigate the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in differentiating benign and malignant ovarian tumors,and analyze the relevant parameters.Methods A total of 89 patients with ovarian tumor admitted to Xingyi People's Hospital from August 2017 to November 2023 were selected,all of which underwent MRI plain scan and DCE-MRI examination.The benign and malignant detection and diagnostic efficiency were analyzed using surgical pathology as the gold standard,and Cohen's Kappa coefficient was used to verify the consistency of differential diagnosis between different methods and the gold standard.The differences of maximum slope of increase(MSI),mean time to enhance(MET),maximum slope of decrease(MSD)and time to peak(TTP)were compared between benign and malignant patients.Results Among the 89 patients,46 were confirmed malignant by operation and pathology,among which 42 were detected malignant by plain MRI and 45 were detected malignant by DCE-MRI.Cohen's Kappa coefficient showed that the Kappa value of MRI plain scan for differential diagnosis was 0.731,which was in good agreement with the gold standard.DCE-MRI differential diagnosis and gold standard Kappa value=0.933,good agreement;The differential diagnosis sensitivity and accuracy of DCE-MRI were higher than that of MRI plain scan(P<0.05).MSI and MSD in malignant patients were higher than those in benign and malignant patients,MET and TTP were shorter than those in benign patients(P<0.05).Conclusion DCE-MRI is of high value in the differentiation of benign and malignant ovarian tumors,which can accurately distinguish benign and malignant,facilitate the early and accurate treatment,and better improve the prognosis of patients.
