目的探讨动态增强磁共振成像(DCE-MRI)与高频超声(HUS)对钙化及非钙化乳腺导管原位癌诊断的敏感性。方法回顾性分析91例乳腺导管原位癌患者的乳腺X线摄影、动态增强磁共振成像(DCEMRI)与高频超声(HUS)的影像表现,运用Mc Nemar检验分析动态增强磁共振成像和高频超声对乳腺DCIS诊断的敏感性。结果动态增强磁共振成像(DCE-MRI)和高频超声检查(HUS)对乳腺导管原位癌的诊断敏感性分别为91.2%,70.3%.对于51例伴钙化及40例不伴钙化组,动态增强磁共振成像的诊断敏感性分别为90.2%,92.5%,高频超声的诊断敏感性分别为76.5%,62.5%.结论动态增强磁共振成像对乳腺导管原位癌的诊断价值优于高频超声。对于不伴钙化组,动态增强磁共振成像对其诊断较高频超声更有帮助。
Objective To investigate the sensitivity of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and high-frequency ultrasound (HUS) in the diagnosis of calcified and noncalcified ductal carcinoma in situ. Methods The imaging findings of mammography, dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) and high-frequency ultrasound (HUS) in 91 patients with ductal carcinoma in situ were retrospectively analyzed. McNemar’s test was used to analyze dynamic contrast-enhanced MR imaging and high frequency Sensitivity of ultrasound to diagnosis of breast DCIS. Results The diagnostic sensitivity of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and high-frequency ultrasonography (HUS) for ductal carcinoma in situ were 91.2% and 70.3% respectively. For 51 patients with calcification and 40 without calcification, The diagnostic sensitivities of dynamic contrast-enhanced magnetic resonance imaging were 90.2% and 92.5%, respectively, and the diagnostic sensitivities of high frequency ultrasound were 76.5% and 62.5% respectively.Conclusions The diagnostic value of dynamic contrast-enhanced magnetic resonance imaging in ductal carcinoma in situ is superior to high Frequency ultrasound. For patients without calcification, dynamic contrast-enhanced magnetic resonance imaging is more helpful for the diagnosis of higher-frequency ultrasound.
