高频超声诊断乳腺小肿瘤的价值

目的探讨高频超声在乳腺小肿瘤早期诊断中的应用价值.方法对124例乳腺良性小肿瘤及恶性小肿瘤患者分别行常规及高频超声检查,并与手术及病理检查结果对照,分析两者不同的声像改变.结果乳腺良性小肿瘤较恶性小肿瘤在肿块形态、边界、包膜声像特征比较差异有统计学意义(P＜0.05),尤其是恶性小肿瘤的微小钙化点检出率46.9%(30/64)与穿支血管检出率78.13%(50/64)较良性小肿瘤的微小钙化点检出率3.3%(2/60)与穿支血管检出率高1.67%(1/60),且差异有非常显著性(P＜0.01).结论常规超声结合彩色多普勒超声检查对小乳癌的早期检出具有重要价值.

The value of high frequency color Doppler ultrasound in the diagnosis of small breast carcinoma

Objective To analyze the sonographic features of small breast carcinoma on conventional gray scale and color Doppler ultrasound with high frequency so as to improve the early detection rate of small breast carcinoma. Methods Overall, 124 cases of small benign or malignant breast tumors were examined by ultrasound and the results were compared with the surgical and pathological findings. The different image features between small benign and malignant breast tumors were analyzed. Results Small benign and malignant breast tumors were significantly different in shape, boundary and capsule (P <0.05). The detection rates of minute calcification and blood vessels of perforating branches of malignant small carcinoma were 46.9 % (30/64) and 78.13 % (50/64), markedly higher than those of benign small tumors, which were 3. 3 % (2/60) and 1. 67 % (1/60), respectively (P < 0. 01). Conclusions The conventional gray scale ultrasound in combination with color Doppler ultrasound examination is of great significance in the early detection of small breast carcinoma.
