In Group I, up to 100 women, at least 40 years of age, who have had a routine standard mammogram read as BI-RADS® 0, 1, 2, or 3 will also undergo 3D breast imaging using a cone beam CT scanner specifically designed to image the breast.
Group II includes forty (40) women, who have had abnormalities detected by physical exam or an imaging modality and are also scheduled for breast biopsy of the index lesion, will also undergo a CBCT of the breast(s), prior to biopsy.
설명
Normal Group:
Inclusion Criteria:
- Are at least 40 years of age of any ethnicity
- Had a routine mammogram, read as BI-RADS® 0, 1, 2 or 3
- Will undergo study imaging no later than six months from date of routine mammogram.
- Is able to undergo informed consent.
Exclusion Criteria:
- Pregnancy
- Lactation
- Patients with physical limitations that may prohibit resting prone on the exam table, such as, but not limited to: frozen shoulder, recent heart surgery, pace maker.
- Patients who are unable to tolerate study constraints.
Patients who have received radiation treatments to the thorax for malignant and nonmalignant conditions, such as (but not limited to)
- Treatment for enlarged thymus gland as an infant
- Irradiation for benign breast conditions, including breast inflammation after giving birth
- Treatment for Hodgkin's disease
- Patients who have participated in a prior breast clinical trial that gave additional radiation dose, such as an additional mammogram.
Patients who have received large numbers of diagnostic x-ray examinations for monitoring of disease such as (but not limited to)
- Tuberculosis
- Severe scoliosis
Diagnostic Group:
Inclusion Criteria:
- Women who are at least 40 years of age of any ethnicity
- Have a palpable abnormality detected by Breast Self Exam (BSE), or Clinical Breast Exam (CBE) or have a non-palpable abnormality detected by an imaging modality
- After diagnostic work-up are categorized as BI-RADS® 4 or 5.
- Are scheduled for biopsy either by large gauge needle biopsy or excisional biopsy.
- Will undergo study imaging prior to biopsy and within four weeks of diagnostic work-up.
Exclusion Criteria:
- Pregnancy
- Lactation
- Patients who have already undergone biopsy for the index lesion
- Patients who are unable or unwilling to undergo biopsy for the lesion of concern
- Patients with physical limitations that may prohibit the patient from resting prone on the exam table, such as, but not limited to: frozen shoulder, recent heart surgery, pace maker.
- Patients who are unable to tolerate study constraints.

Normal Group
In Group I, up to 100 women, at least 40 years of age, who have had a routine standard mammogram read as BI-RADS® 0, 1, 2, or 3 will also undergo 3D breast imaging using a cone beam CT scanner specifically designed to image the breast.
Of these 100, we hope to enroll at least 30 subjects with mammograms read as BI-RADS® 0 and at least 30 read as BI-RADS® 3. The BI-RADS® 0 category refers to patients for whom additional imaging is required after a screening mammogram provided incomplete diagnostic information.

Diagnostic Group
The goals of Group II will be to compare the CBCT study with standard imaging for the diagnosis of breast disease in palpable or non-palpable breast lesions (having a BI-RADS® score of 4 or 5).
Forty (40) women, who have had abnormalities detected by physical exam or an imaging modality and are also scheduled for breast biopsy of the index lesion, will also undergo a CBCT of the breast(s), prior to biopsy.
