超声造影在乳腺良恶性肿瘤鉴别诊断中的价值

目的：探讨超声造影对乳腺良恶性肿瘤的鉴别诊断价值。方法：对55例乳腺肿瘤的患者行二维及彩色多普勒超声检查后,用声诺维SonoVue造影剂进行超声造影检查,记录并分析造影灌注过程。结果：恶性组不均匀增强占86.4%（19/22）,良性组不均匀性增强占15.2%（5/33）,恶性组高增强占68.2%（15/22）,良性组高增强占9.1%（3/33）,恶性组以快进慢退为主（16/22）,良性组以慢进快退为主（16/30）,恶性组不均匀增强明显大于良性组,恶性组高增强明显大于良性组,两者之间的差异有显著性意义（P〈0.05）。结论：超声造影对乳腺肿瘤的诊断提供了更多的信息,提高了诊断的准确率,对于良恶性的鉴别有重要价值。

Significance of Contrast - enhanced Ultrasonography in Differential Diagnosis of Benign and Malignant Breast Tumors

Objective： To explore the value of contrast - enhanced ultrasonography in the differentialdiagnosis between benign and malignant breast tumore. Methods： 55 cases of breast tumors were examined by two - dimensional and color Doppler ultrasonography before operation~ Following the contrast - enhanced ultrasound with contrast agent Sonovue and the perfusion record was analyzed. Results： Inhomogeneous enhancement was in 86.4% （19/22masses） in the malignant group and was 15.2%, （5/33） in the be- nign group ; hyper - enhancement was in 68. 2% （ 15/22masses ） in the malignant group and was 9. 1%, （ 3/33 ） in the benign group; ＂fast in and slow out ＂ in the most malignant group （16/22）, and ＂slow in and fast out＂ In the most benign group （16/30） The hyper and inhomogeneous enhancement of the malignant group was higher than that of the benign group. Conclusions： Contrast -enhanced ultrasonography may provide exact information for the differential diagnosis of benign and malignant breast tumors and be helpful for the differentiation.
