摘要
目的探讨3.0T MRI动态增强扫描结合DWI在乳腺良恶性病变临床诊断中的应用价值。方法 RI动态增强扫描结合DWI,以手术病理结果为基准比较良性及恶性病变患者在MRI影像表现、形态与强化特征方面的差异,计算3.0T MRI动态增强扫描结合DWI诊断乳腺良恶性病变的准确率。结果良性病变患者中边界清晰、形态规则及强化均匀患者所占比例显著高于恶性病变患者,差异有统计学意义(P<0.05)。良性病变患者中,Ⅰ型11例、Ⅱ型26例、Ⅲ型1例,(Ⅰ型+Ⅱ型)占97.4%(37/38);恶性病变患者中,Ⅰ型0例、Ⅱ型4例、Ⅲ型13例,(Ⅰ型+Ⅱ型)占23.5%(4/17),差异有统计学意义(P<0.05)。结论 3.0T MRI动态增强扫描结合DWI在乳腺良恶性病变诊断中的临床应用可实现有效互补,利于诊断准确性的提高,实现良、恶性病变的有效鉴别。
Objective To explore the application value of 3.0T MRI dynamic contrast enhanced scan combined with DWI in the diagnosis of benign and malignant breast lesions. Methods The data of 55 patients with breast lesions treated in our hospital were retrospectively analyzed. All patients underwent 3.0T MRI dynamic contrast enhanced scan combined with DWI. Based on the results of surgery and pathology, the MRI imaging features, morphology and enhancement characteristics were compared between patients with benign and malignant lesions. The accurate rate of 3.0T MRI dynamic contrast enhanced scan combined with DWI in the diagnosis of benign and malignant breast lesions was calculated.Results In patients with benign lesions, the proportion of patients with clear boundaries, regular shape and homogeneous enhancement was significant higher than that in patients with malignant lesions (P〈0.05). In patients with benign lesions, there were 11 cases of type 1, 26 cases of type II and 1 cases of type In, and the proportion of (type I + II) was 97.4% (37/38). In patients with malignant lesions, there was none cases of type 1, 4 cases of type II and 13 cases of type III, and the proportion of (type I + II) was 23.5% (4/17) (P〈0.05). Confirm/on The clinical application of 3.0T MRI dynamic contrast enhanced combined with DWI scan in the diagnosis of benign and malignant breast lesions can achieve effective complementation, which is beneficial to improve the accuracy of diagnosis, and achieve the effective identification of benign and malignant lesions.
