NCT00584233

Brief Summary

The investigators have studied the potential of breast computed tomography (bCT) for breast imaging under an NIH-funded Biomedical Research Partnership (BRP) grant (R01 EB002138-10), and 4 breast CT scanners have been developed that have imaged over 600 women to date (under more than one IRB-approved protocol). The BRP grant cannot be renewed, and with this (resubmitted) R01 grant application, the investigators seek to finalize the investigators' research in breast CT - The specific aims have been significantly modified as a result of the first critique, and the investigators now focus on a narrower set of remaining issues. This version of the protocol will add breast magnetic resonance imaging (MRI) to the experimental procedures.

Outcome Measures

Primary Outcomes (1)

  • Comparison of Pre- and Post- Contrast Breast Computed Tomography With Pre- and Post- Contrast Magnetic Resonance Imaging.

    The specific quantitative endpoint of the analysis is the difference in area under the receiver operating characteristic curve (AUC) between contrast-enhanced breast CT (CE-bCT) and contrast-enhanced breast MRI (CE-bMRI).

    5 years

Study Arms (1)

Breast CT and Breast MRI

EXPERIMENTAL

Four hundred women who will be having breast biopsy as part of their standard care (BIRADS 4 and 5) will undergo pre- and post- contrast breast computed tomography and pre- and post- contrast magnetic resonance imaging.

Device: computed tomographyDevice: MRI

Interventions

Computed tomography of both breasts. For all subjects, CT scanning will be performed before and after an I.V. iodinated contrast injection (100 mL).
