Contact B-mode ultrasonography of masses of the breast is a simple, safe and noninvasive technique which does not involve the use of ionizing radiation. It is highly accurate in differentiating cystic from solid mammary masses measuring 1 centimeter or larger. A biopsy of a sonographically solid mass should be done unless it has an unequivocally benign appearance on mammography. A biopsy of a purely cystic mass, if asymptomatic, need not be done for diagnostic purposes. Needle aspiration can be used as an alternate method for diagnosing a cyst, but failure of this method occurs more often than one is aware of. Sonography is the method of choice for such a diagnosis. Its accuracy in masses 1 centimeter or larger is 100 per cent. When propertly used and carefully correlated with clinical and mammographic findings, it can eliminate over one-third of all operations on the breast.
乳腺肿块的超声B型检查是一种简单、安全且无创的技术，不涉及电离辐射的使用。对于直径1厘米或更大的乳腺肿块，它在区分囊性和实性方面具有很高的准确性。除非在乳房X线摄影上有明确的良性表现，否则对于超声检查为实性的肿块应进行活检。对于无症状的纯囊性肿块，无需为诊断目的进行活检。针吸活检可作为诊断囊肿的替代方法，但该方法的失败率比人们意识到的更高。超声检查是这种诊断的首选方法。其对直径1厘米或更大肿块的诊断准确率为100%。如果使用得当并与临床和乳房X线摄影结果仔细关联，它可以避免超过三分之一的乳腺手术。
