超声造影对乳腺纤维腺瘤和乳腺癌的诊断价值

Analysis of ultrasonographic features and characteristics of acoustic contrast graphs of breast fibroadenoma and breast cancer

目的研究乳腺纤维腺瘤和乳腺癌的超声造影表现，初步探讨超声造影在乳腺良恶性肿瘤鉴别诊断中的应用价值。方法回顾性分析18例乳腺纤维腺瘤和12例乳腺癌的超声造影表现，对比造影前后肿块的超声表现。结果造影后，14例乳腺纤维腺瘤大小测值无明显变化，4例测值增大，5例乳腺癌大小测值无明显变化，7例乳腺癌者大小测值增大；造影后，纤维腺瘤肿块内血管数大部分无明显变化，血管形态较狭窄平直，沿肿块周边走行，乳腺癌肿块内血管数明显增多增粗、迂曲，并有血管进入肿块内。结论超声造影对显示肿块实际大小优于普通超声，造影后肿块大小测值变大、血管数增多、血管不规则走行等以乳腺癌多见。超声造影有利于提高乳腺癌的正确诊断率。

Objective To study the ultrasonographic and acoustic contrast features of breast fibroadenoma and breast cancer and explore the value of contrast enhanced ultrasonography in the differential diagnosis of benign and malignant breast tumors. Method A retrospective analysis of 18 cases breast fibreadenoma and 12 cases breast cancer in the performance of contrast-enhanced ultrasound was done. Results After contrast agent injection, tumor dimension increased in 4 cases with breast fibroadenoma and 7 cases with breast cancer. The ultrasonographie and acoustic contrast features of breast fibroadenoma showed no significant changes. They showed stenosis, perpendicular and circumambulates vascular shape. The breast cancers signifcantly increased the number of tumor blood vessels with the thicker,tortuous blood vessels into the tumor. Conclusions The contrast enhanced ultrasonography assessed more accurate size of tumors. The image displayed grown sizes, more vascularity and bending vascular shape in the breast cancer. It was more accurate than gray-scale ultrasound on diagnosing breast cancer.
