Evaluation of Breast CT

Breast Cancer Clinical Trial

Official title: Evaluation of Breast CT

Status Completed

Clinical Trial 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.

Clinical Trial Description

Clinical evaluation: Four hundred women who will be having breast biopsy as part of their standard care (BIRADS 4 and 5) will be recruited to undergo additional imaging prior to biopsy, including (research) pre-and post-contrast enhanced breast CT imaging of both breasts, as well as (standard, FDA approved) contrast enhanced breast MRI. The potential of non-contrast enhanced breast CT will be compared using receiver operating characteristic (ROC) methodology against mammography alone, as well as with mammography + tomosynthesis. The breast CT images (including both pre-and post-contrast images) will be compared using ROC methodology against standard-of-care contrast-enhanced MRI (which includes both non-contrast and contrast images). The results of the clinical trials proposed in this investigation should provide strong evidence in regards to the potential of breast CT for breast cancer screening in the normal risk and high risk populations. ;
