Current practice in mammographic imaging of the augmented breast in Australia.

aimThis study seeks to document the imaging series used in contemporary Australian practice for imaging the augmented breast, with a secondary focus on differences in practice and opinion between BreastScreen Australia and diagnostic imaging services.

methodsA SurveyMonkey link was distributed through the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) and was assessable during December 2017 and January 2018. The questionnaire investigated: years of experience, facility type and location, image acquisition systems, appointment times, patients imaged per week, technique and imaging series used, use of limited compression views, rationale for variation in imaging series and the use of ultrasound. Descriptive statistics were produced for all variables with chi-squared tests used for comparisons between categorical variables.

resultsThe most frequently used series was the eight-image Eklund ID technique 64% and 59% (submuscular) and 68% and 58% (subglandular) for BSA and diagnostic services, respectively. Eighteen different combinations of projections were reported with eight combinations common to both subglandular and submuscular imaging. The majority of participants attributed imaging series preferences to dose reduction and radiologist preference.

conclusionThis research has demonstrated varied approaches to the routine imaging of women with breast implants and identified the need for the establishment of dedicated evidence-based imaging protocols to ensure that regardless of which setting a woman attends that they receive standardised imaging with minimal dose and maximum breast coverage. This is a reassurance that is not applicable to current practice.
