title: The effect of breast implants on the radiographic detection of microcalcification and soft-tissue masses.
abstract: 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.
