摘　　要：目的探讨磁共振动态增强扫描(DCE-MRI)、磁共振扩散加权成像(DWI)对乳腺癌的诊断价值。方法回顾性抽取2019年8月至2022年4月于南阳市中心医院就诊的疑似乳腺癌患者750例作为研究对象,入院后均行DCE-MRI、DWI检查,以手术病理检查诊断结果为"金标准",分析DCE-MRI、DWI单独及联合检查对乳腺癌的诊断价值。结果经临床病理诊断结果显示,750例疑似乳腺癌患者中,恶性384例,良性366例;经DCE-MRI诊断,良性347例,恶性403例;经DWI诊断,良性358例,恶性392例;经联合诊断,良性382例,恶性368例。DCE-MRI与DWI联合诊断的灵敏度(96.35%,370/382)、准确率(96.53%,724/750)高于DCE-MRI(87.24%,335/384;91.87%,689/750)、DWI(91.15%,350/384;94.40%,705/780)单独检查,漏诊率(3.65%,14/384)低于DCE-MRI(12.76%,49/384)、DWI(8.85%,24/384)单独检查(P<0.05)。结论DCE-MRI联合DWI多模态磁共振检查可有效提高乳腺肿瘤的诊断准确率,有助于临床早期筛查诊断,以便针对性制定个体化治疗方案,改善预后。Objective To investigate the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and magnetic resonance diffusion-weighted imaging(DWI)for breast cancer.Methods A total of 750 patients with suspected breast cancer admitted to Nanyang Central Hospital from August 2019 to April 2022 were retrospectively selected as research objects of the study.All patients underwent DCE-MRI and DWI examinations after admission.Taking diagnostic results of surgical pathological examination as the gold standard,the diagnostic value of DCE-MRI alone,DWI alone,and combination of them for breast cancer was analyzed.Results According to results of clinicopathological diagnosis,among the 750 patients with suspected breast cancer,384 cases were malignant,and 366 cases were benign;according to DCE-MRI examination,347 cases were benign,and 403 cases were malignant;according to DWI examination,358 cases were benign,and 392 cases were malignant;according to combination of DWI and DCE-MRI,382 cases were benign,and 368 were malignant.The sensitivity(96.35%,370/382)and accuracy(96.53%,724/750)of the combination of DCE-MRI and DWI were higher than those of DCE-MRI alone(87.24%,335/384;91.87%,689/750)and DWI alone(91.15%,350/384;94.40%,705/780)in the diagnosis of breast cancer(P<0.05);while the missed diagnosis rate of the combination of DCE-MRI and DWI(3.65%,14/384)was lower than that of DCE-MRI alone(12.76%,49/384)and DWI alone(8.85%,24/384),P<0.05.Conclusions Multimodal magnetic resonance imaging,DCE-MRI combined with DWI,can effectively improve the diagnostic accuracy of breast tumors,and is conductive to early clinical screening and diagnosis,formulation of targeted individualized treatment plans,and improvement of prognosis.
