摘要
目的探讨MR动态增强扫描与钼靶成像在乳腺癌检出率的应用价值。方法本研究搜集2007年6月至2008年5月26例女性患者,所有患者均于术前行钼靶及MRI动态增强扫描,并经手术病理最后诊断。结果全部26例病例,共发现肿块31个。其中浸润性乳腺癌18例,导管原位癌3例,小叶原位癌1例,髓样癌例,粘液癌1例。钼靶检查,共检出肿块24个(77%),确诊乳腺癌20例(64.5%)。MRI动态增强扫描,检出肿块30个(96.8%),经MRI确诊乳腺癌29个(93.5%)。结论MRI动态增强扫描乳腺癌检出率高于钼靶检查,具有较高敏感性,是进行乳腺癌术前评价的有效方法。
Objective To explore the efficacy of digital mammography and dynamiccontrast MRI in the diagnosis of mammary cancer. Methods From June. 2007 to May. 2008 altogether 26 patients taking both digital mammography and dynamic-contrast MRI entered this study. All cases were confirmed by pathology. Results 31 tumors were founded in all 26 cases. There were 18 cases with invasion mammary cancer and 3 cases with ductal carcinoma in situ, 1 case with lobular carcinoma in situ, 3 cases with carcinoma medullare and 1 case with areolar cancer. 24 tumors（77%） were examined in digital mammography and 20 cases were confirmed. 30 tumors（96.8%） were examined in dynamic-contrast MRI and 29 cases were confirmed. Conclusion Dynamic-contrast MRI is more sensitive than digital mammography in detection of breast cancer, which could be effective for pre-operation estimation.
