目的:探讨乳腺MRI与乳腺X线检查在导管原位癌(DCIS)诊断中的应用价值。方法:选择2012年5月至2014年9月在我院接受诊治的乳腺DCIS患者52例(58个病灶)为研究对象,对所有患者进行乳腺MRI及X线检查,以病理检查结果作为金标准,比较乳腺MRI及X线检查在导管原位癌(DCIS)诊断中的应用价值。结果:58个病灶中,乳腺MRI共检查出阳性54例,阴性4例,其中误诊或漏诊4例;乳腺X线共检查出阳性49例,阴性9例,其中误诊或漏诊11例。乳腺MRI检查的灵敏度和准确度均显著高于乳腺X线,差异有统计学意义(P<0.05)。此外,乳腺MRI检查的特异度、阳性预测值及阴性预测值均分别高于乳腺X线,但差异无统计学意义(P>0.05)。结论:乳腺MRI检查对DCIS的诊断价值较高,具有广泛的应用前景,但亦存在少数误诊或漏诊。
Objective: To investigate the value of breast MRI and mammography in the diagnosis of ductal carcinoma in situ (DCIS). Methods: Fifty-two cases (58 lesions) of DCIS patients who underwent diagnosis and treatment in our hospital from May 2012 to September 2014 were selected as the study subjects. All the patients underwent MRI and X-ray examination of breast, and the pathological examination was taken as the gold standard , Comparative breast MRI and X-ray examination in the diagnosis of ductal carcinoma in situ (DCIS) value. Results: Of the 58 lesions, 54 cases were positive by MRI in MRI, 4 cases were negative, of which 4 cases were misdiagnosed or missed. The positive results of mammography were 49 cases and 9 cases were negative, of which 11 cases were misdiagnosed or missed. The sensitivity and accuracy of breast MRI were significantly higher than that of mammography (P <0.05). In addition, the specificity, positive predictive value and negative predictive value of breast MRI were higher than those of mammography, but the difference was not statistically significant (P> 0.05). Conclusion: Breast MRI examination has high diagnostic value for DCIS and has a wide range of applications, but there are also a few misdiagnosis or missed diagnosis.
