摘　　要：目的探讨3.0T MR多模态成像运用于乳腺良恶性病变鉴别诊断中的价值。方法选取我院女性乳腺疾病患者60例,均经病理检验确诊,按检查结果分为良性组(n=44)与恶性组(n=16),两组均接受3.0T MR多模态成像检查,观察各组检查结果。结果所有患者经MRI检查,发现2~3类有42例,4~5类有18例,符合率90.00%(54/60),灵敏度90.91%(40/44),特异度87.50%(14/16),阳性预测值95.24%(40/42),阴性预测值77.78%(14/18)。两组不同b值的ADC差异显著,且恶性组不同b值的ADC均低于良性组(P<0.05)。良性组I型发生率高出恶性组,但II型、III型发生率低于恶性组(P<0.05)。结论3.0T MRI多模态成像检查的效果更好,能更准确鉴别乳腺疾病的良恶性。Objective To study the value of 3.0T magnetic resonance(MRI)multimodal imaging in the differential diagnosis of benign and malignant breast lesions.Methods 60 female patients with breast diseases included in our hospital from January to December 2020 were diagnosed by pathological examination.According to the examination results,they were divided into benign group(n=44)and malignant group(n=16).Both groups underwent 3.0T MRI multimodal imaging,and the examination results of each group were observed.Results After MRI examination,42 patients with grade 2~3 and 18 patients with grade 4~5 were found.The coincidence rate was 90.00%(54/60),the sensitivity was 90.91%(40/44),the specificity was 87.50%(14/16),the positive predictive value was 95.24%(40/42),and the negative predictive value was 77.78%(14/18).The ADC of different b values in the two groups were significantly different,and the ADC of different b values in the malignant group was lower than that in the benign group(P<0.05).The incidence of type I in benign group was higher than that in malignant group,but the incidence of type II and type III was lower than that in malignant group(P<0.05).Conclusion The effect of 3.0T MRI multimodal imaging is better,which can more accurately identify the benign and malignant breast diseases,and it is worth popularizing.
