摘要

目的:探讨MR扩散加权成像与不同成像序列联合应用对乳腺良恶性病变定性诊断价值。方法:回顾性分析71例(良性42例46个病灶,恶性29例32个病灶)经手术及病理证实乳腺良恶性病变患者的MRI资料,以病理诊断为金标准,统计并比较T1WI结合DWI(T1WI+DWI)、T2WI结合DWI(T2WI+DWI)、DCE、DCE结合DWI(DCE+DWI)这4种诊断方式对乳腺良恶性病变诊断的敏感性、特异性及准确性。结果:T1WI+DWI、T2WI+DWI、DCE、DCE+DWI这4种诊断方式对乳腺良恶性病变诊断的敏感性分别为81.3%、90.6%、93.7%、96.8%,特异性分别为73.9%、91.3%、89.1%、93.5%,准确性分别为76.9%、91%、91%、94.9%。结论:DCE联合DWI对诊断乳腺良恶性病变有较高的敏感性、特异性及准确性,对乳腺良恶性病变的诊断与鉴别诊断具有很高的临床价值,是最佳诊断组合序列。非增强组合序列对乳腺良恶性病变的诊断有一定优势,可作为乳腺疾病筛查的MRI技术。

Abstract

Objective: To evaluate the value of MR diffusion weighted imaging and different sequences combinations the qualitative diagnosis of breast benign and malignant lesions. Methods: A retrospective analysis of 71 cases(46 benign cases with 46 lesions, 29 malignant cases with 32 lesions) MRI data of patients with breast benign and malignant lesions diagnosed by surgery and pathology. Base on the pathological diagnosis as the gold standard, we use the four ways of diagnostic modality(T1WI+DWI, T2WI+DWI, DCE, DCE+DWI) to compare the sensitivity, specificity and accuracy of diagnosis for breast benign and malignant lesions. Results: The diagnose sensitivity of the T1WI+DWI, T2WI+DWI, DCE and DCE+DWI were 81.3%, 90.6%, 93.7%, 96.8%, and their specificity were 73.9%, 91.3%, 89.1%, 93.5% and their accuracy were 76.9%, 91%, 91%, 94.9%. Conclusion: The diagnosis of breast benign and malignant breast lesions in DCE combined DWI group has a higher sensitivity, specificity and accuracy of diagnosis. So that has a clinical value, is the best combinations diagnostic sequences. Non-enhancement combinations sequences has a certain advantages in the diagnosis, it could be used as a MRI technology to screening breast disease.
