How does the chest X-ray look like after breast implants removal?

The larger the breast implants, the smaller the woman and the longer the implants were on the chest may result in permanent skin and rib changes which MAY be seen on a chest X ray. Any calcifications in the scar around the implants which is left behind may be seen on such as film. Same with any indentations in the ribs.But to the trained eye of a Radiologist such changes are rarely confusing and suggestive of other diseases.

Simply stated it is very unlikely a prior history of breast implants will affect the diagnostic quality of your chest X-ray.  However, it is possible the remaining breast implant pocket capsule harbors some calcifications, which would be visible on X-ray.  The body forms a capsule around any implanted non biologic material, including breast implants.  Most surgeons do not excise the capsule when removing breast implants unless there is an obvious problem.  And most times it is rare that breast capsules develop calcifications because modern implants are much better quality.  At the surgery to remove your implants, if your surgeon found no problems with implant (e.g. leak) and no signs of significant capsule abnormality, it is very unlikely an X-ray will show evidence of prior breast implants.
