Current implants for breast augmentation containing silicone gel, saline, or both can totally obscure mammographic detection of microcalcifications and soft-tissue masses. To investigate the possibility of developing a more radiolucent implant, radiographs were obtained of silicone shells that contained silicone gel, saline, silicone gel and saline, polyurethane-covered silicone gel, gelatin, sunflower oil, and peanut oil. All radiographs were obtained using a Siemens Mammomat by placing the implant over an American College of Radiology mammography phantom. Results were measured by the ability to visualize or resolve the artifacts in the mammography phantom. The silicone shell alone minimally altered artifact resolution. Silicone shells filled with silicone gel, silicone gel and saline, saline alone, polyurethane-covered silicone gel, and gelatin were equal in radiodensity and completely obscured all phantom artifacts. Silicone shells filled with peanut oil and sunflower oil had equal radiodensity and allowed visualization of large microcalcifications and some soft-tissue masses. Current implants used for augmentation mammaplasty can totally obscure mammographic detection of microcalcifications and soft-tissue masses. A more radiolucent breast implant is possible, and further research is needed to define the best filler material and test its biocompatibility.
目前用于隆胸的植入物含有硅胶、盐水或两者皆有，这可能会完全掩盖乳房X光检查对微钙化和软组织肿块的检测。为了研究开发一种射线可透过性更强的植入物的可能性，我们对含有硅胶、盐水、硅胶和盐水、聚氨酯覆盖的硅胶、明胶、葵花籽油和花生油的硅胶外壳进行了X光片拍摄。所有X光片均使用西门子乳腺机拍摄，将植入物放置在美国放射学会乳腺摄影体模上。通过在乳腺摄影体模中观察或分辨伪影的能力来衡量结果。单独的硅胶外壳对伪影分辨率的影响最小。填充有硅胶、硅胶和盐水、仅盐水、聚氨酯覆盖的硅胶以及明胶的硅胶外壳在射线密度上相同，完全掩盖了所有体模伪影。填充有花生油和葵花籽油的硅胶外壳射线密度相同，能够观察到大型微钙化和一些软组织肿块。目前用于隆乳术的植入物可能会完全掩盖乳房X光检查对微钙化和软组织肿块的检测。一种射线可透过性更强的乳房植入物是有可能的，需要进一步研究来确定最佳填充材料并测试其生物相容性。
