10MHz高频超声诊断乳腺肿块的应用价值

本文采用１０ＭＨｚ超声探头检查１１０例经手术与病理学确诊的乳腺肿块，观察其声像特征，探讨乳腺良、恶性肿块的鉴别指标。１１０例中乳腺良性肿块９２例。其中，良性乳腺增生病１９例，炎性肿块３例，纤维腺瘤６８例及乳汁郁积性囊肿２例。超声诊断符合率９３．４％。另１８例为恶性肿块，其中导管浸润癌１２例，单纯癌２例，髓样癌２例，硬癌１例及导管乳头状瘤局部恶变１例。超声诊断联合率为９４．４％。作者认为１０ＭＨｚ探头分辨力高，能清楚显示乳腺与乳腺肿块细微结构的声像改变，发现小于１ｃｍ的乳腺肿块。通过声像改变判定乳腺肿块的形态、边缘是否光整、有无包膜回声、肿块内部回声分布是否均匀、肿块后方有无声衰减以及是否向周围组织浸润等指标，有助于乳腺良、恶性肿块的鉴别。

A STUDY ON 10 MHz PROBE IN THE ULTRASONOGRAPHIC DIAGNOSIS OF BREAST MASSES

This paper reported 110 cases with breast masses which were examined by a high resolution 10 MHz probe and were verified by operation and pathological examination. 92 of 110 cases were benign breast masses among which 19 were benign breast hyperplasia, 3 were inflammative masses, 68 were fibroadenoma and 2 were galactocele. The ultrasonographic diagnostic correct rate of benign breast masses was 93.4%. 18 of 110 cases were malignancy. 12 were infiltrating duct carcinoma, 2 were caroinoma simplex, 2 medullary carcinoma, one scirrhous carcinoma and another one duct papilloma with canceration. The ultrasonographic diagnostic correct rate was 94.4%.It was suggested that the ultrasonic image provided by a 10 MHz probe is good enough to assess the subtle echo changes of the breast and breast masses.
