BreastScreen Victoria pilot trial of the feasibility and outcomes of tomosynthesis (3D-mammography) screening at Eastern Health

None listed

This pilot study will assess the feasibility and the outcomes of using digital breast tomosynthesis (3D-mammography) for routine breast screening. Who is it for? You may be eligible to join this study if you are a woman aged 40 years or above and are attending a BreastScreen service at Maroondah BreastScreen. Study details Women who attend for routine breast screening will have an opportunity to have tomosynthesis screening (3D-mammography acquisition with synthetic 2D-mammography) in place of standard 2D-mammography, those declining to participate will have standard 2D-mammography. 3D mammography screening involves having x-rays of both breasts (taken as two views of each breast, with the breast transiently compressed similarly to conventional 2D mammograms). There are two mammography units that operate at the Maroondah service, both units can perform 2D screens however only one unit can perform 3D acquisitions. If the woman consents to participating, she will then receive either 2D or 3D acquisition, this being by chance of which mammography unit is available when they are taken into the screening procedure. All other aspects of screening, reading and assessment, and any required follow-up, will be based on standard BreastScreen protocols and quality assurance processes. Screening detection measures and feasibility of using 3D mammography will be assessed. It is hoped that this pilot feasibility study will inform planning of future larger studies using 3D mammography or further evaluation in BreastScreen Australia.
