摘要
目的:评价MRI动态增强在乳腺良恶性疾病诊断中的意义及临床应用价值。方法:收集本院2010年7月～2011年10月临床门诊或钼靶检查有或疑似有乳腺肿块的乳腺疾病患者38例共74个乳腺,进行MRI动态增强并经病理证实的乳腺病变进行分析研究。结果:38例患者中病理结果为良性者17例(19枚病灶),乳腺恶性病变21例(25枚病灶)。MRI动态增强正确诊断良性病变14例(15枚病灶),恶性病变20例(24枚病灶);MRI动态增强对乳腺恶性肿瘤检出的敏感度、特异度和诊断符合率达95.2%、82.4%和89.5%。结论:MRI动态增强能显示乳腺内恶性肿瘤的形态学特征,反映病灶血流动力学变化,对乳腺恶性肿瘤有较高的诊断价值。
Objective ：To evaluate the diagnostic value and clinical significance of dynamic contrast-enhanced MR imaging（DCEMRI） in benign of malignant mammary lesions. Methods ： Between Jul. 2010 and Oct. 2011, 38 patients （74 mammary glands） with suspicious mammographic or pal- pable mass findings underwent DCEMRI examination and pathological confirmation, and the data were reviewed for comparison of the final diagnosis. Results： The pathologic results revealed benign lesion in 17 cases （ 19 lesions ） and malignancy in 21 （ 25 lesions ） malignant findings, whereas DCEMRI led to final diagnosis of benign lesion in 14 （lesions） and malignancy in 20 （24 lesions）. The sensitivity, specificity and accura- cy by DCEMRI was 95. 2%, 82. 4% and 89. 5%, respectively. Conclusion ： DCEMRI has a higher value in the diagnosis of breast cancer,for it can naturally reveal the morphological fashion and hemodynamic changes of the diseased mammary glands.
