【摘要】 目的　探讨对比运用 2 0MHz与 7.5MHz高频超声对乳腺病变进行诊断的临床价值。方法　分别应用 2 0MHz与 7.5MHz的探头检查 30例患者乳腺病变的形态、大小及血流状况。结果　 2 0MHz超高频超声对乳腺导管内乳头状瘤或癌伴乳腺导管扩张、乳腺肿块内沙粒状钙化灶、肿块边界蟹足状改变及包膜样回声以及乳腺皮肤弥漫性或结节性病灶检出率高于 7.5MHz高频超声。结论　 2 0MHz超高频超声对乳腺内小病变的检查具有重要价值 ,特别是在乳腺导管内乳头状瘤或癌伴乳腺导管扩张、乳腺肿块内沙粒状钙化灶的检查中具有重要特征。更多还原

【Abstract】 Objective To investigate the clinical value in the diagnosis of breast disease with 20 MHz and 7.5 MHz high frequency sonography comparatively. Methods Breast diseases of 30 cases were scanned with 20 MHz and 7.5 MHz sonography separately. The breast lesions were described according to shape, size and blood flow. Results Compared to 7.5 MHz sonography, 20 MHz high frequency sonography is of a higher visibility of breast intraductal papilloma or carcinoma with duct dilatation, capsular-like echo and infiltrating boundary and micro-calcification of breast mass and diffuse or nodular lesions of breast cutis. Conclusion 20 MHz high frequency sonography has great value in the visibility of breast mass,particularly in breast intraductal papilloma or carcinoma with duct dilatation and micro-calcification of breast mass.更多还原
