What can they see on mammogram if I have breast implants?

Most everything. Implants are known not to affect mammograms for the most part, particularly if they are placed under muscle. However moving the implant from the x-ray field is needed to view every quadrant of breast tissue, which can occasionally be difficult for the radiology technologist.
Normal breast tissue. After having implants placed, you should get yearly screening mammograms. Implants are inserted behind the pectoralis muscle so it does not interrupt the breast tissue. When you get a mammogram, there are ways to "displace" the implant so the breast tissue can be evaluated. Remember to perform monthly self breast exams. Get a digital mammogram.
Breast & implant. Mammography is a very good screening exam for the breasts and should be the first step in radiographic breast screening for women around age 40. The presence of breast implants necessitates certain special displacement (eklund) views to be sure to visualize as much of the breast as possible.
Extra precautions. Currently mammograms are the standard, extra views such as ecklund compression are used to attempt to displace the implant and increase visualization of the breast tissue which may be obscured by the presence of the implant. Ultrasound may be used. Mris are increasingly more popular for imaging breasts and more sensitive for tumor dectection although self exam remains the keystone for detection.
Breast tissue. Breast implants can interfere with visualization of breast tissue during mammography studies; this interference tends to be less with implants placed in the sub muscular position as opposed to the sub glandular position. Special “displacement techniques” are used to better visualize breast tissue during mammography.
Implants. There is no difference in the accuracy. However, the implant mammography study will be twice as many views as the standard mammo, because they will need to do special views to displace the implants.
