Breast ultrasound (US) was performed, with either an automated or a hand-held unit or both, on 1,212 patients. Of 612 asymptomatic patients, 118 (19.3%) had solitary cysts; ten (1.6%), multiple cysts; and 29 (4.7%), benign masses; however, US depicted only one (0.2%) nonpalpable mammographically undetected carcinoma. In 513 patients with palpable masses (n = 396) and with mammographically detected masses (n = 117), US was useful in avoiding an unnecessary biopsy in 113 (22.0%), leading to aspiration of a cyst in 26 (5.1%), monitoring multiple cysts in 31 (6.0%), avoiding aspiration of a solid mass in 65 (12.7%), supporting biopsy of an equivocal solid mass in 91 (17.7%), and demonstrating a nonpalpable mammographically detected carcinoma in six (1.2%). In 224 patients with either palpable or mammographically visible masses who underwent both methods of US, the 4.5-MHz or 3.9-MHz automated unit depicted the abnormality in 119 (53.1%) and the 7.5-MHz hand-held unit, in 171 (76.3%). Of 18 cancers evaluated with both methods, all were detected with the hand-held unit and only 12 were seen with the automated unit.
对1212例患者进行了乳房超声（US）检查，使用的是自动或手持设备，或两者皆用。在612例无症状患者中，118例（19.3%）有孤立性囊肿；10例（1.6%）有多个囊肿；29例（4.7%）有良性肿块；然而，超声仅发现1例（0.2%）乳房X线摄影未检测到的不可触及的癌。在513例有可触及肿块的患者（n = 396）和乳房X线摄影检测到肿块的患者（n = 117）中，超声在以下方面发挥了作用：113例（22.0%）避免了不必要的活检，26例（5.1%）引导了囊肿穿刺，31例（6.0%）监测多个囊肿，65例（12.7%）避免了实性肿块穿刺，91例（17.7%）支持对可疑实性肿块进行活检，6例（1.2%）发现了乳房X线摄影检测到的不可触及的癌。在224例有可触及或乳房X线可见肿块且接受了两种超声检查方法的患者中，4.5兆赫或3.9兆赫的自动设备检测到异常的有119例（53.1%），7.5兆赫的手持设备检测到异常的有171例（76.3%）。在使用两种方法评估的18例癌症中，所有癌症均由手持设备检测到，而自动设备仅检测到12例。
