Magnetic resonance imaging (MRI), mammography and ultrasonography were performed in 44 consecutive women (mean age 45 [29-70] years) with a total of 73 silicone breast implants. The implant had been inserted after mastectomy for cancer in 15 patients, for cosmetic breast augmentation in 29. MRI proved to be superior to the other two imaging modalities with respect to assessing implant content, capsule and surrounding tissues. In 39 patients MRI clearly demarcated the implant from the residual breast tissue. But in four patients the lateral MRI assessment was impaired by phase artefact and in one other by movement artefacts in a restless patient. Implant thickness was underestimated by mammography and ultrasonography compared with MRI. In nine cases mammography showed retromammary parenchyma, while MRI did so in 20. The posterior wall of the implant was visualized by mammography in only one patient, but in all of them by MRI. Ultrasonography failed in all patients to show the entire implant circumference. In three cases MRI was the only imaging method which revealed a defect in the implant capsule with extrusion of silicone.
对连续44名(平均年龄45岁[29 - 70岁])共植入73个硅胶乳房假体的女性进行了磁共振成像(MRI)、乳房X线摄影和超声检查。其中15例患者在因癌症行乳房切除术后植入假体,29例为美容性隆乳。在评估假体内容物、包膜及周围组织方面,MRI被证明优于其他两种成像方式。在39例患者中,MRI能清晰地将假体与残留乳腺组织区分开。但有4例患者的MRI外侧评估受相位伪影影响,另有1例因患者躁动出现运动伪影而影响评估。与MRI相比,乳房X线摄影和超声检查低估了假体厚度。乳房X线摄影在9例中显示了乳腺后实质,而MRI在20例中显示了该情况。乳房X线摄影仅在1例患者中显示了假体后壁,而MRI在所有患者中均显示了该后壁。超声检查在所有患者中均未能显示假体的整个周长。在3例中,MRI是唯一显示假体包膜有缺陷且硅胶挤出的成像方法。
