摘　　要：目的 探讨X线乳腺钼靶联合磁共振成像(MRI)常规序列与扩散加权成像(DWI)序列在乳腺癌诊断中的应用效果。方法 回顾性分析2021年2月至2023年2月我院收治的80例乳腺病变患者临床资料,所有患者均接受X线乳腺钼靶、MRI检查,以病理结果为金标准,判断两者单一检查与联合检查的诊断效能,并分析不同病变X线钼靶、MRI影像学特征。结果 经病理研究结果证实,良性病变36例,乳腺癌44例,X线乳腺钼靶、MRI检查及两者联合检查灵敏度、特异度、准确度分别为88.89%、79.55%、83.75%与94.44%、86.36%、90.00%、97.22%、95.45%、95.25%。乳腺癌MRI征象中边缘不规则、形状分叶状、强化不均匀、TIC曲线流出型比例均高于良性病变患者,ADC值低于良性病变患者,差异有统计学意义(P<0.05)。结论 X线乳腺钼靶联合MRI常规序列+DWI序列检查对乳腺癌诊断准确率较高,具有较好临床应用价值。Objective To investigate the application of mammography combined with conventional magnetic resonance imaging(MRI) sequences and diffusion weighted imaging(DWI) sequences in the diagnosis of breast cancer.Methods The clinical data of 80 patients with breast lesions admitted to the hospital from February 2021 to February 2023 were analyzed retrospectively.All patients underwent mammography and MRI examination.Pathological results were taken as the golden standard to analyze the diagnostic performance of the two methods and their combination.The mammography and MRI features of different lesions were analyzed.Results Pathological results confirmed 36 cases of benign lesions and 44 cases of breast cancer.the sensitivity,specificity and accuracy of mammography,MRI,and their combination were(88.89%,79.55% and 83.75%),(94.44%,86.36% and 90.00%),and(97.22%,95.45% and 95.25%),respectively.The proportions of MRI signs(irregular margin,lobulated shape,inhomogeneous enhancement and outflow type TIC) in breast cancer were higher than those in benign lesions,and the ADC value was lower than that of benign lesions(P<0.05).Conclusion Mammography combined with conventional MRI sequence and DWI sequence is relatively accurate in diagnosing breast cancer.
