目的探讨超声对小乳癌(≤2cm)的诊断价值。方法将B超诊断为良性乳腺肿块的32例与乳癌的30例经病理证实后,回顾总结超声声像图特征。结果小乳癌的超声声像图具有形态不规则、轮廓锯齿状毛刺样、无包膜或壁、内有微钙化灶、纵横比值≥1等五项特征(其中以内有微钙化灶为重要表现)。结论乳腺肿块内有微钙化灶等五项特征是超声诊断小乳癌有价值的依据。
Objective To investigate the diagnostic value of ultrasonography for small breast cancer (≤2cm). Methods After diagnosing 32 cases of benign breast mass by B ultrasound and 30 cases of breast cancer by pathology, the features of ultrasonography were reviewed and summarized. Results Ultrasound sonography of small breast cancer with irregular shape, profile jagged burr-like, no capsule or wall, there are micro-calcifications, the aspect ratio of ≥ 1 and other five features (of which micro-calcification within the important performance) .
