摘要
目的：探讨声学造影在乳腺肿块定性诊断中的应用价值。方法：对62例乳腺肿块（33例良性，29例恶性）进行声学造影检查，通过观察造影增强模式、分析时间-强度曲线参数比较乳腺良恶性肿块的差异。结果：良、恶性肿块造影增强均匀度、造影增强时间、达峰时间、斜率有显著差异（P<0.05）；峰值强度、峰值～60s平均强度及峰值～60s曲线下面积无明显差异。把肿块不均匀增强、造影剂出现时间<10s，达峰时间<20s，斜率<5作为恶性参考指标。对于乳腺肿块灰阶及彩色多普勒确诊率88.7%，结合声学造影确诊率93.6%。结论：声学造影有助于提高乳腺肿块定性的确诊率。
Abstract
Objective: To evaluate the diagnostic value of contrast-enhanced ultrasound in the diagnosis of breast lesions. Methods: Sixty-two cases of breast lesions, in which 33 cases were benign, and 29 were malignant, were examined with contrast-enhanced ultrasound. The enhancement pattern, time-intensity curve and contrast parameters were analyzed to compare the differences between benign and malignant lesions. Results: Significant differences were found in homogeneity of the intensity, the initial enhancement time, peak time and the slope rate(all P<0.05). No significant difference were found in peak intensity, average intensity and areas under peak～60s of the time-intensity curves. The inhomogenity of the intensity, the time from initial enhancement<10s, peak time <20s and the slope rate<5 were set as the indicators for malignancy. The diagnostic accuracy of B-ultrasound and color Doppler flow imaging is 88.7%, when combined with contrast-enhanced ultrasound, the diagnostic value can be improved to 93.6%. Conclusions: Contrast-enhanced ultrasound can improve the accuracy of diagnosis for breast lesions.
