Primary Outcome Measures:
  • 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.

Groups/Cohorts Assigned Interventions
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.
Radiation: computed tomography (CT scan)
Subjects will undergo cone beam breast CT scan
Other Name: 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.
Device: computed tomography (CT scan)
Subjects will undergo cone beam breast CT scan
Other Name: CT scan
