目的 :揭示超声在乳癌诊断中的价值 ,提高诊断水平。方法 :分析 1997年 1月至 2 0 0 0年4月间 74例经手术病理或穿刺活检证实为乳癌患者的高频声像图和彩色多普勒特征。结果与结论 :常见恶性乳腺肿块的高频声像图特征 :形态不规则 ,边界不清 ,回声不均 ,多为低回声 ,部分伴有钙化灶 ,后方衰减 ,中、晚期病例可见周边小病灶和同侧腋窝甚至锁骨上淋巴结转移。在应用彩色多普勒观察时 ,可见肿瘤内的血管明显增多 ,且肿瘤越大血流信号越丰富。对个别超声印象不典型的病例或为便于制定手术方案 ,缩短患者手术时间 ,可实施超声引导下穿刺活检。
Objective: To reveal the value of ultrasound in the diagnosis of breast cancer and improve the diagnostic level. Methods: From January 1997 to April 2004, 74 patients with breast cancer confirmed by pathology or biopsy underwent high-frequency ultrasonography and color Doppler imaging. RESULTS AND CONCLUSION: The features of high frequency sonography of common malignant breast masses are irregular, unclear boundary, unequal echoes, mostly hypoechoic echo, partially calcified foci, and posterior decay. In the middle and late stage, small peripheral lesion and Side axillary or supraclavicular lymph node metastasis. In the application of color Doppler observation, visible blood vessels within the tumor increased significantly, and the greater the tumor, the more abundant blood flow signals. On the individual cases of atypical ultrasound imaging or to facilitate the development of surgical options to shorten the operation time of patients, the implementation of ultrasound-guided biopsy.
