摘　　要：目的探讨动态对比增强磁共振成像(dynamic contrast-enhanced magnetic resonance imag⁃ing,DCE-MRI)+钼靶X线诊断乳腺小结节良恶性的价值。方法随机选取枣庄市市中区人民医院2020年1月—2022年12月收治的100例乳腺小结节患者作为研究对象,所有患者均接受DCE-MRI、钼靶X线检查。以病理检查结果为诊断的金标准,分析DCE-MRI、钼靶X线及两者联合诊断乳腺小结节良恶性的效果。结果病理的检查结果显示,40例为恶性结节,60例为良性结节。DCE-MRI+钼靶X线的灵敏度(95.00%)、特异度(98.33%)以及准确度(97.00%),相比于DCE-MRI、钼靶X线单独诊断更高,差异有统计学意义(χ^(2)=12.921、6.411、12.615,P均<0.05)。DCE-MRI+钼靶X线对于浸润性导管癌、导管内原位癌、乳房佩吉特病合并导管原位癌的诊断符合率相比于DCE-MRI、钼靶X线单独诊断均更高,差异有统计学意义(P均<0.05)。结论相比于DCE-MRI或钼靶X线,DCE-MRI+钼靶X线诊断恶性乳腺小结节的灵敏度、特异度以及准确度更高,可为临床提供理论参考。Objective To investigate the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)+molybdenum target X-ray in the diagnosis of benign and malignant breast nodules.Methods 100 patients with breast nodules admitted to the People's Hospital of Shizhong District,Zaozhuang City from January 2020 to December 2022 were selected as the study subjects.All patients underwent DCE-MRI and molybdenum target X-ray examination.Using pathological examination results as the gold standard for diagnosis,analyze the effectiveness of DCE-MRI,molybdenum target X-ray,and their combined diagnosis for benign and malignant breast nodules.Results The pathological findings showed that 40 cases were malignant and 60 cases were benign.The sensitivity,specificity and accuracy of DCE-MRI+molybdenum target X-ray were 95.00%,98.33%and 97.00%,respectively,higher than those of DCE-MRI and molybdenum target X-ray sigle diagnosis,the differences were statistically significant(χ^(2)=12.921,6.411,12.615,all P<0.05).The diagnostic coincidence rate of DCE-MRI+mammography for invasive ductal carcinoma,intraductal carcinoma in situ,Paget disease combined with ductal carcinoma in situ were higher than those of DCE-MRI and molybdenum X-ray sigle diagnosis,the differences were statistically significant(all P<0.05).Conclusion Compared to DCE-MRI or molybdenum target X-ray,DCE-MRI+molybdenum target X-ray has higher sensitivity,specificity,and accuracy in diagnosing malignant breast nodules,providing theoretical reference for clinical practice.
