Study summary

The purpose of this study is to conduct an initial investigation into whether an alternative method of using 3D imaging might offer accurate diagnostic performance at a reduced patient radiation exposure in comparison to conventional 2D screening and diagnostic mammography and conventional 2D + 3D imaging methods.

Inclusion criteria

  • Subject is female of any race and ethnicity
  • Subject is at least 40 years old
  • The screening and diagnostic mammograms were performed at the recruiting institution on a Hologic Selenia System
  • Subject is categorized as BI-RADS 0 because if mass, density, or calcifications detected on the basis of screening or diagnostic mammography
  • Subject will undergo study imaging within 30 days of standard of care imaging

Exclusion criteria

Exclusion Criteria:

  • Patients who are pregnant or think they may be pregnant
  • Patients who are breast feeding
  • Subjects unable or unwilling to undergo
  • Subjects with breast implants
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    3D investigational imaging

    patients returning with an area of interest will undergo investigational 3D imaging in 2 modes of imaging to the breast of interest and compare to the subjects standard of care imaging

    Device: 3D mammograpgy system

Interventions

  • Device3D mammograpgy system

    In addition to the standard care diagnostic imaging, all participants underwent two experimental acquisitions, in two projections (Cranio-Caudal and Mediolateral Oblique) on the breast of concern: one acquisition in Mode A (narrow angle acquisition) and one acquisition in Mode B (wide angle acquisition). The experimental imaging is compared to the standard of care imaging

    Also known as: Selenia Dimensions, Tomosynthesis

What researchers measure

Primary outcomes

  1. If the new imaging modes are successful, they will represent a method of reducing patient exposure for future imaging because they are designed to be used in 3D imaging only.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
