The role of ultrasound imaging in the diagnosis of breast implant rupture: a prospective study.

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.
