乳腺良恶性肿瘤的超声诊断价值

Applied value of Ultrasonography in the Diagnosis of Breast Tumor

目的探讨乳腺良性肿瘤，恶性肿瘤的二维和彩色多谱勒超声的特征性改变。方法超声检查120例乳腺肿块，分析良性肿瘤与恶性肿瘤的声像图特点。结果乳腺恶性肿瘤形态不规则，边界呈毛刺状，无完整包膜，肿块内微钙化、“恶性晕”征及穿通血管的检出率明显高于良性肿瘤。结论乳腺肿块超声检查探查到微钙化／“恶性晕”征／穿通血管，常常提示为乳腺癌，超声检查对乳腺肿瘤的诊断与鉴别诊断有重要价值。

Objective To investigate the characteristic changes of benign and malignant breast lesions by two-dimensional and color Doppler flow imaging （CDFI） . Methods Fifty-six cases with breast carcinoma and sixty-four with benign lesion were examined by ultrasound and compared with the result of surgery and pathology. Results Most of the malignant lesions were shown irregular shape and spinous edge, with incomplete or without capsule. The most outstanding ultrasonographic features of the breast malignancy were with micro-calcification and malignant halo and perforating blood vessels in the tumor, the detectable rate were differed significant from the benign lesions. Conclusions Micro-calcification and perforating blood vessels in breast mass strongly suggested the diagnosis of breast cancer. The ultrasound is of great value in differential diagnosis of breast lesion.
