彩色多普勒超声与MR诊断乳腺病变的临床价值分析

目的：比较彩色多普勒超声、磁共振动态增强对乳腺病变的临床诊断价值。方法收集经手术与病理证实的95例同时做过超声与M R的101个乳腺病灶，对其二维声像图及CDFI特点与磁共振动态增强影像学表现，对照病理结果进行回顾性分析。结果彩色多普勒与MR动态增强扫描对乳腺良恶性病变定性诊断准确率分别为：超声良性病变诊断正确率73．3％，恶性病灶诊断正确率87．3％；M R良性病变诊断正确率84．3％，恶性病灶诊断正确率92．7％。95个患者共检出101处病灶，其中乳腺癌67例，占66％；纤维瘤23例，占23％，炎性肉芽肿4例，占4％；分叶状肿瘤2例，占2％；囊腺瘤1例，占1％；乳头状瘤4例，占4％。结论超声检查诊断准确性高，适用于乳腺疾病的常规检查；MR空间分辨力及软组织分辨力高，适用于超声检查难以定性的病变及乳腺癌的术前评估。

Comparing the diagnostic value of Color Doppler ultrasound and magnetic resonance imaging in breast lesions

Objective To compare the clinical diagnostic value of Color Doppler ultrasound and dynamic contrast-en-hanced MRI in breast lesions .Methods 95 patients （101 breast lesions） ,confirmed by surgery and pathology ,and re-ceived both Color Doppler ultrasound and MRI were collected .Compared with the pathological results ,two-dimensional sonogram ,color Doppler flow imaging features and Dynamic contrast-enhanced MRI findings were retrospectively ana-lyzed .Results Qualitative diagnosis accuracy of Color Doppler ultrasonography and Dynamic contrast-enhanced MRI in Benign and Malignant Breast Tumor ：Doppler ultrasonography diagnostic accuracy of benign lesions is 73 .3% ,and 87 .3%in malignant lesions ;Dynamic contrast-enhanced M RI diagnostic accuracy of benign lesions is 84 .3% ,and 92 .7% in ma-lignant lesionsis .101 Breast lesions were diagnosed in 95 patients ,including 67 cases of breast cancer ,accounting for 66% ;23 cases of fibroma ,accounting for 23% ;4 cases of inflammatory granuloma ,accounting for 4% ;2 cases of phyl-lodes tumour ,accounting for 2% ;1 case of cystic adenoma ,accounting for 1% ;4 cases of papilloma ,accounting for 4% . Conclusion Color Doppler ultrasonography has high diagnosis accuracy ,and suitable for the routine examination of breast disease;with high spatial resolution and soft tissue resolution ,MR is suitable for breast lesions ,which is difficult to be qualitatively dignosised by Color Doppler ultrasonography ,and preoperative evaluation of breast cancer .
