目的 :探讨乳腺导管内乳头状瘤的高频彩超声像图表现。方法 :采用 10 MHz探头及彩色多普勒超声 (CDFI) ,对 15例手术病理证实的乳腺导管内乳头状瘤进行观察。结果 :高频彩超诊断乳腺导管内乳头状瘤 11例 ,诊断符合率为 73%。乳腺导管不规则扩张呈局限性内有中强回声团 ,迭加 CDFI,仅 2例有点状血流信号 ,1例有条状血流信号。结论 :高频彩超可以显示扩张的导管及导管内瘤体的特征 ,CDFI检测肿块内多数无血流信号 Objective: To investigate the high frequency color Doppler sonography of intraductal papillomatosis. Methods: Fifteen cases of intraductal papilloma confirmed by surgery were observed with 10 MHz probe and color Doppler sonography (CDFI). Results: High frequency color Doppler ultrasound diagnosis of intraductal papilloma in 11 cases, the diagnostic coincidence rate was 73%. Irregular dilatation of breast duct was limited within the strong echo group, superimposed CDFI, only 2 cases had a bit of blood flow signal, 1 case of a strip of blood flow signal. Conclusion: High-frequency color Doppler ultrasound can show the characteristics of the dilated duct and intraductal tumor. CDFI detects the majority of blood flow-free signals
