Breast ultrasound to assess possible implant rupture was performed on 24 consecutive patients (43 breasts) by the same radiologist immediately before revisional breast implant surgery. Comparison of the clinical, ultrasound and operative findings showed ultrasound to be three times as sensitive as clinical judgement in predicting implant rupture. The sensitivity of ultrasound in predicting impaired implant integrity was 70% (versus 23% for clinical examination) with a specificity of 96%. The ultrasound features indicating leakage are outlined later. The positive predictive value of an abnormal scan was 90% and that of a normal scan 87%. It is concluded that breast ultrasound is a simple, quick, non-invasive method which contributes significantly to the assessment of patients with suspected breast implant rupture.
在连续24例患者（43个乳房）进行乳房假体修复手术前，由同一位放射科医生立即进行乳房超声检查，以评估可能的假体破裂情况。临床、超声和手术结果的比较显示，在预测假体破裂方面，超声的敏感性是临床判断的三倍。超声预测假体完整性受损的敏感性为70%（临床检查为23%），特异性为96%。提示渗漏的超声特征将在后面概述。异常扫描的阳性预测值为90%，正常扫描的阳性预测值为87%。结论是，乳房超声是一种简单、快速、无创的方法，对疑似乳房假体破裂患者的评估有显著帮助。
