Mammography is _______ if the implant is subpectoral rather than subcutaneous.

Mammography is _______ if the implant is subpectoral rather than subcutaneous.

• A. worse
• B. better
• C. unchanged
• D. not feasible

Answer: (B)

Understanding how implant location affects mammographic visualization is key. When an implant sits under the pectoralis muscle (subpectoral), it lies behind the breast tissue rather than directly behind it. That means the radiopaque implant is less likely to overlay and obscure the posterior breast tissue on standard views, and imaging can more effectively separate the implant from the glandular tissue. With appropriate implant-displacement views (moving the implant back and pulling the breast tissue forward), the native tissue can be seen with less interference. In contrast, a subcutaneous (directly behind the breast tissue) implant sits in the same plane as the glandular tissue, causing more superimposition and radiopaque shadowing. This makes detecting abnormalities harder, so imaging is less optimal. Therefore, mammography tends to be better when the implant is subpectoral.
