乳腺良恶性病灶的影像学鉴别及诊断分析

目的比较MRI与乳腺X线钼靶在鉴别诊断乳腺良恶性病灶中的应用价值。方法回顾性分析2013年5月-2015年5月我院收治且经病理诊断确诊为乳腺肿瘤的78例患者的临床资料,其中良性乳腺肿瘤34例,恶性44例,所有患者入院后均已接受乳腺数字化钼靶及MRI检查,分析MRI及钼靶在乳腺良恶性病灶鉴别诊断中的应用价值。结果 78例乳腺病变乳腺钼靶患者检出良性30例,恶性48例,其诊断良恶性乳腺病变敏感性、特异性及准确性分别为80.0%、79.2%、79.5%;MRI检出良性病变34例,恶性病变44例,诊断良恶性乳腺病变敏感性、特异性及准确性分别为88.2%、91.7%、89.7%。结论在乳腺良恶性病变鉴别诊断中,MRI敏感性、特异性、准确性均高于钼靶。乳腺钼靶在诊断乳腺微小钙化灶方面有其优势,但MRI动态增强扫描可清晰显示乳腺软组织结构、性状、边缘、血管强化特点及早期强化特征,提高良恶性病变的检出率。

Imaging Differentiation and Diagnosis of Benign and Malignant Breast Lesions

Objective To compare the application value of MRI and molybdenum target mammography in the differential diagnosis of benign and malignant breast lesions. Methods The clinical data of 78 patients with breast tumors confirmed by pathology treated in our hospital from May 2013 to May 2015 were analyzed retrospectively. Among them, 34 cases were with benign breast tumors and 44 cases with malignant ones. All patients received breast digital molybdenum target mammography and MRI examination after admission. The application value of MRI and molybdenum target mammography in the differential diagnosis of benign and malignant breast lesions was analyzed.Results Among the 78 cases of breast lesions, 30 cases of benign and 48 cases of malignant breast lesions were detected by molybdenum target mammography. The sensitivity, specificity and accuracy of it in the diagnosis of benign and malignant breast lesions were 80.0%, 79.2% and 79.5% respectively; MRI detected 34 cases of benign lesions and 44 cases of malignant lesions. The sensitivity, specificity and accuracy of MRI the diagnosis of benign and malignant breast lesions were 88.2%, 91.7% and 89.7% respectively.Conclusion The sensitivity, specificity and accuracy of MRI are higher than those of molybdenum target in the differential diagnosis of benign and malignant breast lesions. Breast molybdenum target mammography has its advantages in the diagnosis of small calcification but the MRI dynamic enhanced scan can clearly show the structure, character, edge, enhancement features of blood vessel and early enhancement features of breast soft tissues and improve the detection rate of benign and malignant lesions.
