旨在分析乳腺病灶声象图的特征，以压缩中间型（不能区分良恶性）的声象图诊断。将２８３例经手术和病理证实的乳腺病灶的声象图，按１０个征象标准，分归五类不同的诊断级：Ａ级肯定良性；Ｂ级倾向良性；Ｃ级良、恶性无法区别；Ｄ级倾向恶性；Ｅ级肯定恶性。重点分析Ｃ级的２３例声象图。结果：提出完整的包膜回声线是良性病灶的主要征象；而边缘不规则、毛刺，不均质低回声和衰减则是恶性病灶的三个特征。结论：熟悉各类病变独有的声象图特征；对彩色多普勒血流图恰当的评价；分析时抓住主要征象，就能减少中间型声象图的诊断。
The aim was to analyze the characteristics of the sonographic image of breast lesions and to diagnose the sonograms of the compressed intermediate type (cannot distinguish between benign and malignant). The sonograms of 283 cases of breast lesions confirmed by surgery and pathology were classified into five different diagnostic levels according to 10 criteria: A grade was positively benign; grade B was benign; C grade benign and malignant were indistinguishable; D Grade tends to be malignant; E grade is definitely malignant. Focus on the analysis of 23 cases of C-class sonograms. RESULTS: The complete envelope echo line was the main sign of benign lesions; irregular edges, burrs, inhomogeneous hypoechoic and attenuation were three features of malignant lesions. Conclusions: Familiar with the unique features of various types of lesions; appropriate assessment of color Doppler flow; analysis of the main signs, you can reduce the diagnosis of intermediate acoustic image.
