Imaging in patients with breast implants—results of the First International Breast (Implant) Conference 2009



The First International Breast (Implant) Conference was held by the EAoS® (European Academy of Senology) in cooperation with the German Society of Senology during its 29th annual meeting in Düsseldorf, Germany, on 13 June 2009.


It was performed as a whole-day interactive workshop in which the standards of implant surgery within reconstructive and aesthetic breast surgery were discussed and defined by telecommunication dialogue voting.


This article describes the conference results concerning pre- and post-procedural imaging in patients with breast implants. Both before and after augmentation, imaging is mandatory and provides essential information concerning tissue and implant integrity. Whereas mammography is the first-line method before surgery, ultrasound is the mainstay of post-procedural imaging. Cancer screening in augmented breasts generally follows the same guidelines as for non-augmented breasts.


Whereas agreement about the indications for mammographical and sonographical evaluations is largely unanimous, there was substantial disagreement as far as the application of magnetic resonance imaging is concerned. There is an obvious demand for an evidence-based evaluation of this modality and the implementation of appropriate guidelines.


Breast implant insertion has evolved as a largely established and accepted modality for reconstruction after mastectomy, correction of congenital malformations and cosmetic augmentation of the breast [1]. The procedural volume of alloplastic breast implant reconstruction and augmentation is high, and it will further increase in the future. According to benchmark studies of the West German Breast Center [2], the mastectomy rate in Germany is currently about 35%, resulting in about 15,000–25,000 mastectomies per year. In addition to this figure, there is an ever-increasing demand for cosmetic breast implantation that has led to a dramatic rise in procedure numbers in the past 2 decades [3, 4]. To date, breast augmentation with single lumen silicone implants—currently the ‘gold standard’ of augmentation—is the single most common cosmetic procedure in the UK [5].

There are a number of issues that may require diagnostic imaging in patients with breast implants:

  • Regular screening mammography

  • Additional imaging for BI-RADS 0, III, IV and V lesions

  • Interventional biopsy

  • Specific implant-related complications such as abnormal immune response or connective tissue diseases [6] and implant-associated tumors [7]

  • Implant leakage or rupture [8]

Patients with breast implants present the radiologist with specific challenges, such as the identification and distinction of implant and breast tissue, diagnosis of implant defects and implant-related complications as well as diagnosis and follow-up of unrelated breast diseases such as mastitis or breast cancer [9]. The fact that an increased mortality due to malignant disease has been described among patients with breast implants [10] may indicate specific diagnostic difficulties, and indeed a decreased sensitivity of mammography in patients with silicone implants has been described [11].

Whereas this indicates the necessity of a differential diagnostic approach to breast imaging in patients with implants—and quite likely a more central role for magnetic resonance imaging—there are currently no widely accepted guidelines. Therefore, interactive consensus decisions were sought.

Consensus decisions of the First International Breast (Implant) Conference 2009, Düsseldorf

The expert panel consisted of 26 invited renowned experts from 5 countries (Germany, n = 20; USA, n = 2; Austria, n = 2; UK, n = 1; Italy, n = 1), including one of the pioneers of breast implantology (Dr. Thomas Biggs, Houston), the director of one of the busiest centers (Dr. Brian Kinney, Los Angeles) and the entire European panel of senior breast augmentation surgeons.

The consensus decisions were considered after a presentation of the best available evidence on each issue, a full-day discussion thereafter and a 2-day workshop focussing on the topic.

Decisions were made by means of telecommunication dialogue (TED) voting, i.e. each participant pushed the appropriate one of three buttons on a remote control device after a question was projected on-screen.

The conference decisions concerning imaging in patients before implant insertion or with implants, respectively, are displayed in Table 1.

Imaging before implant insertion

In general, a majority of attendees considered imaging before breast implantation as a necessity [except for very few exceptions, e.g., in very young women (<25 years) without specific risk factors], and bidirectional mammography in combination with ultrasound is the preferred modality. There are several reasons to recommend some form of imaging before breast augmentation, with the possibility of opportunistic cancer detection being just one of them. The other key reasons that make breast imaging before augmentation practically mandatory are

  • exclusion of suspicious lesions prior to surgery and

  • diagnosis and documentation of pre-existing tissue alterations such as microcalcifications, etc.

Even if the latter are no reason for immediate further diagnostic and/or therapeutic measures, the documentation may be of crucial clinical—and forensic—importance if and when malignant lesions intercurrently occur in the augmented breast [12].

The general diagnostic properties of mammography and ultrasound determine that both methods should be employed in this order, just as in breast cancer screening. Sophisticated MR imaging and CAD calculation of implant size and shape [13] are currently uncommon; MRI is only employed by 9%, but may become more important in the future.

Imaging after implant breast reconstruction following mastectomy

After mastectomy, the reconstructed breast is mostly examined by ultrasound (90%), whereas MRI (42%) and especially mammography (9%) are substantially less frequently recommended. This preference is quite obvious and mainly dictated by the anatomical circumstances after mastectomy where both MRI and mammography are impractical because of the lack of mammary gland tissue.

Imaging after implant breast augmentation

After breast augmentation, imaging as such was stipulated unanimously, and there are two main and equally important indications for this: Diagnostic workup of possible implant rupture and ongoing breast cancer screening and diagnosis in implant-bearing patients. In general, ultrasound and—to a somewhat lesser extent—mammography were named as the methods of choice. Once again, MRI played an almost negligible role.

This opinion is well in line with the diagnostic requirements in patients after breast augmentation: The major specific complication is intra- or extra-capsular implant rupture, which occurs in up to 50% of women with augmented breasts within 12 years [14]. Studies on newer “third generation” implants suggest a lower failure rate of about 15% within 10 years [15], but considering the high (and increasing) number of women with implants, rupture must be considered a frequent condition. Implant rupture has well-defined and discernible sonographic features, i.e. the classical “snowstorm” appearance with dense acoustic shadowing [16]. A completely negative ultrasound examination has a very high predictive value for implant integrity [17], limiting the application of mammography or MRI to sonographically suspicious cases [5].

Although ultrasound diagnosis of implant failure is basically feasible, MRI evaluation is frequently recommended [16] and may become more important in the future [9, 18]. Presently, MRI is recommended in the diagnostic workup of clinically or sonographically suspicious cases, but not in asymptomatic women without previous conventional imaging [19], and an evidence-based assessment of its superiority over sonography in terms of diagnostic accuracy would be required to justify the general recommendation of the substantially more expensive MRI.

The second important issue in post-implant imaging is breast cancer screening and diagnosis. The suspected relationship between breast implants and cancer has essentially been disproved, but considering the high number of women with implants, cancer diagnosis in the augmented breast is a major issue [15, 20]. The mainstay of tumor screening and diagnosis in the augmented breast is—just as in non-operated patients—mammography and ultrasound in that order [22]; however, the sensitivity of both methods for cancer detection may be reduced in augmented breasts [11, 21], and patients ought to be informed of this fact before they undergo surgery. Therefore, the re-evaluation with MRI—which is discussed elsewhere in this paper—may become more important in augmented breasts, but currently the literature provides no sufficient evidence for its recommendation [21].

Three-dimensional ultrasound may become a basis of contemporary postoperative breast implant evaluation, thus providing a combination of medical diagnosis and aesthetic assessment for which so far only a few relatively demanding methods are available [2325]; however, there is presently no evidence of this application of available breast scanner systems.

Interventional biopsies in patients with breast implants

A substantial majority considered interventional biopsies in the augmented breast basically feasible and would only occasionally and upon necessity resort to open procedures. Since implants present very well on sonography and other imaging modalities, a decline in the number of interventional biopsies would hardly be justified. However, an interventional core needle biopsy has to be performed with particular care in order to avoid iatrogenic implant rupture [22].

Application of MRI after implant insertion

The value of MRI after breast augmentation is the one issue of substantial controversy. Almost regardless of the respective application, the number of votes for and against MRI in the panel discussion were equal. The only situation where most participants agreed about MRI making sense was a suspicion of tumor in the augmented breast, and this view is in accordance with the literature [e.g., 9, 18, 19, 26]. However, MRI is currently considered to be a second-line method to be applied after mammography has yielded a suspicious result that could not be verified or falsified by ultrasound examination or in cases of peri-implant positivity at clinical examination with inconclusive results of conventional imaging [19, 22]. The same applies to the diagnosis of implant rupture where the value of MRI is undeniable, but its application limited to cases with inconclusive results of conventional imaging [5, 9, 26, 27]. Presently, the literature provides no evidence for the recommendation of MRI for screening purposes in patients with augmented breasts as given by the US Food and Drug Administration [28].


  1. 1.

    Before breast augmentation, imaging is strongly recommended for most women. It will mainly follow the same guidelines as in routine mammography screening, i.e. mammography followed by ultrasound if necessary. Findings that don’t require immediate diagnostic or therapeutic action should be thoroughly documented.

  2. 2.

    Following augmentation after mastectomy, imaging is also a necessity, but ultrasound is the method of choice due to morphological and practical considerations.

  3. 3.

    The follow-up of previously healthy augmented breasts is guided by two rationales: diagnosis of complications (i.e., mainly rupture) and cancer screening. For the former, ultrasound examination is the current method of choice, whereas cancer screening in augmented breasts requires mammography.

  4. 4.

    Interventional biopsies in augmented breasts can and should be performed under more or less the same guidelines as in non-augmented breasts.

  5. 5.

    The role of MRI in the evaluation of breast implant-bearing patients is possibly emerging, but presently controversial. Controlled trials with high methodological standards will be required to better define its specific values and to implement evidence-based guidelines; however, sonography and mammography still provide a very satisfactory basis.
