Correlation between mammography and breast CT on lesion detection [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
There are two specific aims of this pilot study. One specific aim is to determine if the lesions that are detected by mammography and referred for biopsy, are visible with breast CT. The other specific aim is to determine if there is a correlation between CT numbers and malignancy, in particular for soft tissue (solid masses) abnormalities and to determine if image processing techniques improve correlation between CT numbers and malignancy.

Role of 3D Tomography in Breast Cancer
Role of 3D Tomography in Breast Cancer

The primary aim of this pilot study is to define the role of dedicated cone beam breast computed tomography in breast cancer imaging. This research is a prelude of a more comprehensive clinical trial that may follow.

Non-Probability Sample

Women, age 40 or older, who are scheduled for biopsy after classification as BI-RADS 4/5 and have had a screening or diagnostic full-field digital mammography (FFDM) exam, and who meet the inclusion criteria, are eligible to participate.

Breast Cancer
  • Radiation: computed tomography (CT scan)
    Subjects will undergo cone beam breast CT scan
    Other Name: CT scan
  • Device: computed tomography (CT scan)
    Subjects will undergo cone beam breast CT scan
    Other Name: CT scan
  • Group I Microcalcifications
    After classification as BI-RADS 4/5, approximately 75 to 100 subjects with primary findings based on microcalcifications will be recruited to have a breast CT scan.
    Intervention: Radiation: computed tomography (CT scan)
  • Group II Soft tissue findings
    After classification as BI-RADS 4/5, approximately 75 to 100 subjects with primary soft tissue findings, with or without associated microcalcifications, will be recruited to have a breast CT scan.
    Intervention: Device: computed tomography (CT scan)
