摘　　要：目的探讨T_(2) mapping序列结合表观扩散系数(ADC)值在鉴别乳腺良恶性病变中的价值。方法回顾性选取乳腺肿块患者92例,所有患者均行MRI检查,图像分析选择T_(2) mapping序列与ADC值,且均经手术活检、病理诊断,观察T_(2) mapping序列结合ADC值鉴别诊断乳腺良恶性病变的临床价值。结果经病理检查显示,52例确诊为乳腺恶性病变,其余40例确诊为乳腺良性病变。52例恶性病变患者中,经ADC值诊断为恶性51例,诊断为良性1例。40例良性病变中,ADC值诊断为恶性16例,诊断为良性24例。乳腺良性病变与恶性病变的T_(2)值的均值相比差异无统计学意义(P>0.05);但乳腺恶性病变的T_(2)值离散系数(CV)明显高于乳腺良性病变,差异有统计学意义(P<0.05),T_(2) mapping与ADC值单一检查方法诊断效能均低于联合检查(P<0.05)。结论MRI中T_(2) mapping序列和ADC值均具有诊断和鉴别乳腺良恶性的能力,尤其是二者联合应用的价值更加突出,提升诊断准确度、敏感度、特异度,可为临床提供更加准确的参考信息,值得推广。Objective To investigate the value of T_(2) mapping sequence combined with apparent diffusion coefficient(ADC)values in identifying benign and malignant breast lesions.Methods Ninety-two patients with breast mass were retrospectively selected,all patients received MRI examination,T_(2) mapping sequence and ADC values were selected for image analysis,and all patients underwent surgical biopsy and pathological diagnosis,the clinical value of T_(2) mapping sequence combined with ADC values in differential diagnosis of benign and malignant breast lesions was observed.Results After pathological examination,52 patients were diagnosed as malignant breast lesions and the remaining 40 were diagnosed as benign breast lesions.Among 52 patients with malignant lesions,51 were diagnosed as malignant and 1 was diagnosed as benign by ADC values.Among the 40 cases of benign lesions,16 were diagnosed as malignant and 24 were diagnosed as benign by ADC values.The difference between the mean T_(2) values of benign breast lesions and malignant breast lesions was not significant(P>0.05);but the coefficient of variation(CV)of T_(2) values of malignant breast lesions was significantly higher than that of benign breast lesions,and the difference was significant(P<0.05),and the diagnostic efficacy of T_(2) mapping and ADC value single examination was lower than that of the combined examination(P<0.05).Conclusion T_(2) mapping sequence and ADC value in MRI have the ability to diagnose and distinguish benign and malignant breast,especially the value of the joint application of the two is more prominent,improve the diagnostic accuracy,sensitivity and specificity,and can provide more accurate reference information for clinical practice,which is worth popularizing.
