Cone Beam Computed Tomography for Breast Imaging

Koning Corporation401 enrolled

Overview

The primary aim of this study is to continue the investigation of cone beam computed tomography (CBCT) for breast imaging already underway in the diagnostic setting by providing a compelling body of evidence incorporating non-contrast CBCT in the study protocol. The goal is to accumulate a body of evidence to provide data to incorporate CBCT into the diagnostic work-up of breast lesions.

Interventions

Computed TomographyDEVICE

In Group I, fifty CBCT studies will be performed. The objectives will be to illustrate the capacity of CBCT to image the breast in its entirety as compared with the gold standard mammographic exam.

Computed TomographyDEVICE

In Group II , at least three hundred and fifty (350) study participants, who require diagnostic evaluation of the breast will undergo a breast CBCT . These subjects may be referred for biopsy as a result of a finding from a mammogram, ultrasound, MRI, or clinical exam.

Outcomes

Primary Outcomes

Concordance and discordance of CBCT imaging with diagnostic mammography, other breast-imaging modalities, and histopathology

The primary measure of this study will include the following aspects. * the capacity of CBCT to image the breast in its entirety as compared with the gold standard mammographic exam * patient's comfort during the CBCT exam vs the mammographic exam * the concordance and discordance of CBCT breast imaging with standard mammography and other breast-imaging studies * the concordance and discordance of CBCT breast imaging with histopathology * number of participants with adverse events as a measure of safety
