摘　　要：目的:分析磁共振扩散加权成像(DWI–MRI)联合全数字化乳腺摄影(FFDM)检查对乳腺病变定性诊断的价值。方法:选取厦门大学附属第一医院2019年4月至2021年3月收治的乳腺病变患者86例,均行DWI–MRI、FFDM单独及联合检查,以病理诊断为金标准,统计DWI–MRI、FFDM单独及联合检查结果、乳腺病变类型,并比较诊断效能,分析不同b值乳腺病变表观扩散系数(ADC)值。结果:DWI–MRI联合FFDM诊断准确度、灵敏度较DWI–MRI、FFDM单独诊断高,漏诊率较DWI–MRI、FFDM单独诊断低,差异具有统计学意义(P<0.05);b=400 s·mm^(-2 )、b=800 s·mm^(-2 )、b=1000 s·mm^(-2 )恶性病灶ADC值均低于良性病灶,差异具有统计学意义(P<0.05)。结论:DWI–MRI联合FFDM应用于乳腺病变鉴别诊断,可提高准确度、灵敏度,降低漏诊率,提供病灶详细信息,有助于临床诊疗方案的制定以及预后评估。Objective To analyze the value of magnetic resonance diffusion weighted imaging(DWI-MRI)combined withfull-field digital mammography(FFDM)in the qualitative diagnosis of breast lesions.Methods 86 patients with breast lesions treated in the First Affiliated Hospital of Xiamen University from April 2019 to March 2021 were examined by DWI-MRI and FFDM separately and jointly.Taking pathological diagnosis as the gold standard,the results of DWI-MRI and FFDM alone and jointly and the types of breast lesions were counted,the diagnostic efficacy was compared,and the apparent diffusion coefficient(ADC)of breast lesions with different b values were analyzed.Results The diagnostic accuracy and sensitivity of DWI-MRI combined with FFDM were higher than DWI-MRI and FFDM alone,and the missed diagnosis rate was lower than DWI-MRI and FFDM alone(P<0.05).The ADC values of malignant lesions with b=400 s·mm^(-2 ),b=800 s·mm^(-2 )and b=1000 s·mm^(-2 )were lower than those of benign lesions(P<0.05).Conclusion The application of DWI-MRI combined with FFDM in the differential diagnosis of breast lesions can improve the accuracy and sensitivity,reduce the missed diagnosis rate,provide detailed information of lesions,and contribute to the formulation of clinical diagnosis and treatment plan and prognosis evaluation.
