Cone Beam Computed Tomography for Breast Imaging

June 14, 2013 updated by: Koning Corporation
The primary aim of this study is to continue the investigation of cone beam computed tomography (CBCT) for breast imaging already underway in the diagnostic setting by providing a compelling body of evidence incorporating non-contrast CBCT in the study protocol. The goal is to accumulate a body of evidence to provide data to incorporate CBCT into the diagnostic work-up of breast lesions.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

The study population will be selected from the patient population at a community based clinic, Elizabeth Wende Breast Care, LLC, which is located in Rochester, NY. Group I will consist of subjects who have had mammograms read as BIRADS® 1 or 2. Group II will be subjects who have had a diagnostic mammogram read as BIRADS® 4 or 5 prior to breast biopsy.

Inclusion Criteria:

Group I:

  • Females at least 35 years of age of any ethnicity
  • Had a mammogram, read as BI-RADS® 1 or 2
  • Will undergo study imaging no later than four weeks from date of mammogram.
  • Is able to undergo informed consent.

Group II:

  • Females at least 35 years of age of any ethnicity
  • Require diagnostic imaging
  • Will undergo study imaging no later than four weeks from date of diagnostic mammogram
  • Is able to undergo informed consent

Exclusion Criteria:

Group I and Group II:

  • Pregnancy
  • Lactation
  • Subjects 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.
  • Subjects who are unable to tolerate study constraints.

  • Subjects 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 Hodgkins disease
  • Subjects who have participated in a prior breast clinical trial that gave additional radiation dose, such as an additional mammogram.

  • Subjects who have received large numbers of diagnostic x-ray examinations for monitoring of disease such as (but not limited to)

    • Tuberculosis
    • Severe scoliosis

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Group I
Device: Computed Tomography
In Group I, fifty CBCT studies will be performed. The objectives will be to illustrate the capacity of CBCT to image the breast in its entirety as compared with the gold standard mammographic exam.
Device: Computed Tomography
In Group II , at least three hundred and fifty (350) study participants, who require diagnostic evaluation of the breast will undergo a breast CBCT . These subjects may be referred for biopsy as a result of a finding from a mammogram, ultrasound, MRI, or clinical exam.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Concordance and discordance of CBCT imaging with diagnostic mammography, other breast-imaging modalities, and histopathology
Time Frame: about 3 years

The primary measure of this study will include the following aspects.

  • the capacity of CBCT to image the breast in its entirety as compared with the gold standard mammographic exam
  • patient's comfort during the CBCT exam vs the mammographic exam
  • the concordance and discordance of CBCT breast imaging with standard mammography and other breast-imaging studies
  • the concordance and discordance of CBCT breast imaging with histopathology
  • number of participants with adverse events as a measure of safety
about 3 years
