隆乳术后假体破裂是一个重要的并发症。尽管已证明乳腺X线摄影、干乳X线摄影、超声、热成像和计算机断层扫描（CT）等几种技术可用于检测植入物破裂，但它们存在几个缺点，且缺乏特异性。在目前的研究中，我们已经建立了磁共振成像（MRI）作为一个明确的，可靠的，可重复的技术来诊断囊内和囊外破裂。该研究在100名有症状的患者中进行。我们的成像参数能够识别硅胶壳植入物的破裂。所有破裂均显示存在波浪线、凝胶内自由浮动的硅胶壳（“自由浮动松线征”或“扁线征”）。我们有3.75%的假阳性和假阴性结果发生率。检测硅胶植入体破裂的灵敏度为76%，特异性为97%。此外，我们还能够识别可能干扰植入物破裂明确诊断的伪影。（Plast。重建92：681，1993）。
Breast implant rupture is an important complication of augmented and reconstructed breasts. Although several techniques such as mammography, xeromammography, ultrasound, thermography, and computed tomographic (CT) scanning have been proven to be useful to detect implant rupture, they have several disadvantages and lack specificity. In the current study, we have established magnetic resonance imaging (MRI) as a definitive, reliable, and reproducible technique to diagnose both intracapsular and extracapsular ruptures. The study was conducted in 100 symptomatic patients. Our imaging parameters were able to identify ruptures in implants with silicone shells. All the ruptures showed the presence of wavy lines, free-floating silicone shell within the gel (“free-floating loose-thread sign” or “linguine sign”). We had a 3.75 percent incidence of false-positive and false-negative results. The sensitivity for detection of silicone implant rupture was 76 percent, with a specificity of 97 percent. In addition, we also were able to identify the artifacts that may interfere with the definitive diagnosis of implant rupture. (Plast. Reconstr. Surg. 92: 681, 1993.)
