A breast implant is a prosthesis used to change the size, shape, and contour of a person's breast. In reconstructive plastic surgerybreast implants can be placed to restore a natural looking breast mound for post— mastectomy breast reconstruction patients or to correct congenital defects and deformities of the chest wall. They are also used cosmetically to enhance or enlarge the appearance of the breast through breast augmentation surgery.
The Augmented Breast More thanwomen in the United States undergo an augmentation mammoplasty annually. Two studies 12 have reported the incidence of implants in American women to range from 3. The augmented breast presents a challenge to the radiologist to image the residual parenchyma adequately and to detect any abnormalities.
Radiological Diagnosis of Breast Diseases pp Cite as. It is difficult to obtain high-quality mammograms. Features uniquely inherent to the breast, such as shape, size, density, and low contrast, combine with patient factors such as anxiety, tenderness, and fear of radiation to challenge the skills of the best-trained technologist.

It consists of posterosuperior displacement of the implants simultaneously to an anterior traction of the breast, pushing the implants towards the chest wall up to flatten. It is a complex technique that requires a significant sensitivity and skill by mammographers. Helps image portion of breast that escape visualization due to superimposing implant.
The number of women undergoing breast implant procedures is increasing exponentially. It is, therefore, imperative for a radiologist to be familiar with the normal and abnormal imaging appearances of common breast implants. Diagnostic imaging studies such as mammography, ultrasonography, and magnetic resonance imaging are used to evaluate implant integrity, detect abnormalities of the implant and its surrounding capsule, and detect breast conditions unrelated to implants.
However, due to the implant, several special mammography views must be taken to allow visualization of both the breast tissue and the implant. For this reason, diagnostic mammography is usually performed on patients with breast implants as opposed to screening mammography that is typically performed on asymptomatic women without implants. Examination of the augmented breasts is more time consuming; therefore, the imaging location performing the mammography should be informed of the presence of implants when the mammogram is scheduled. Patients with implants should also inform the physician and the technologist performing the exam that they have implants.
Breast implants are composed of saline, silicone or a combination of both and are placed in sub-glandular or sub-pectoral location. To determine whether the implant is retroglandular or sub-muscularthe medio-lateral oblique MLO view on mammogram is more useful as it shows optimum imaging of pectoralis muscle. Breast implants may be used in conjunction with breast reconstruction after mastectomy.
Breast Cancer Diagnosis, Prognosis, and Treatment in Augmented Women Neal Handel Introduction Over the years concerns have been raised about the possible effects of silicone implants on the incidence, detection, treatment, and prognosis of breast cancer. Since breast augmentation is popular, these are legitimate questions. Recent statistics published by the American Society of Aesthetic Plastic Surgery ASAPS indicate breast augmentation is the most popular cosmetic surgical procedure in the United States; nearlyprimary breast augmentations were performed in 1.
