摘要 目的探讨动态增强MRI在乳腺良恶性病变鉴别与诊断中的应用价值。方法分析80例乳腺病变患者临床影像学资料,并以手术病理诊断为金标准。结果经手术病理诊断发现,其中良性病变者35例,恶性病变者45例。良性病变者毛刺状及边缘不规则者明显少于恶性病变者,P<0.05;良性病变者边缘形态主要表现为光滑。恶性病变者A型者明显多于良性病变人群,然良性病变者C型者较恶性病变者多,P<0.05。良性病变者早期MRI增强率以<60%为主,而恶性病变者以≥60%为主。结论应用动态增强MRI可有利于医生鉴别乳腺良恶性病变患者病灶形态,同时信号强度时间曲线和早期增强率可辅助临床疾病诊断。 Objective To investigate application value of dynamic enhanced MRI in the differentiation and diagnosis of benign and malignant breast lesions. Methods The clinical and imaging data of 80 patients with breast lesions diagnosed with pathology as the golden standard were retrospectively analyzed in this work. Results By means of pathology,35 cases were diagnosed with benign lesions and 45 cases with malignant lesions. Benign lesions presented with burr shape and irregular edges are significantly less than malignant lesions( P〈0. 05). The smooth edge was the major manifestation of benign lesions. Type A in malignant lesions was more than that in benign lesions,but,type C in benign lesions was much less than malignant lesions( P〈0. 05).MRI enhancement rate in early benign lesions was less than 60% and that in malignant lesions was equal to or more than 60%.Conclusion Application of dynamic enhanced MRI can help doctors identify patients with breast benign and malignant lesions and,at the same time,the signal intensity curve and early enhancement rate can assist doctors make disease diagnosis in clinic.
