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

Abstract

BackgroundThe 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.MethodsIt 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.ResultsThis 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.ConclusionWhereas 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.

Estudio multicéntrico prospectivo observacional sobre implantes PIP® colocados en 12 años

“…Según Embrey y col. (9), el porcentaje de sensibilidad en la detección de anomalías estructurales en implantes mamarios mediante mamografía es del 83%, 75% para la resonancia magnética (RM) y 50% para el ultrasonido, con una especificidad del 43% frente al 71% de la RM y el 40% de la mamografía. Por otro lado, en la Guía de la Primera Conferencia Internacional de Implantes Mamarios celebrada en el 2009 (18,19), se recomienda el ultrasonido mamario como mejor método de estudio postquirúrgico para la evaluación de rotura de los implantes. Este último informe validaría nuestros hallazgos en los que el ultrasonido mamario presentó un 93% de sensibilidad y un 97% de especificidad para evaluar la integridad de los implantes.…”

Removing silicone artifacts in diffusion-weighted breast MRI by means of shift-resolved spatiotemporally encoding

“…It includes a FatSat pulse; an initial slice-selective p/2 excitation; a diffusion weighting block where bipolar gradient pulses of duration d are separated by a diffusion time D; a SPEN module including an adiabatic p sweeping in the presence of a gradient G e a FOV defined by the adiabatic frequency range cG e FOV (and thereby introducing a quadratic evolution phase / e (r) / r 2 along the encoding gradient's direction) (29,44,45); and an acquisition including an oscillating 6G ro gradient providing a modulation that when subject to Fourier Transform (FT) gives the spatial profile along the readout axis, interspersed with blipped G a gradients resolving the position of each SPEN-encoded spin packet. Focusing on the acquisition along the latter axis only, the ensuing signal is of the form SðtÞ / Dr Á X sites Vcs Z FOV r cs ðV cs ; rÞ Á exp ½iðf e ðrÞ þk a ðtÞr þ V cs tÞdr [1] where Dr ¼ ffiffiffiffiffiffiffiffiffi ffi…”

Imaging of breast implants—a pictorial review

“…Up to half of all ruptures in women with augmented breasts occur within 12 years [1]. Intracapsular implant rupture is defined as rupture of the implant shell with silicone leakage that does not macroscopically extend beyond the fibrous capsule.…”
