Trial summary

The primary goal of this study is to compare, within a clinical screening setting, the performance of stereoscopic digital mammography with standard (non-stereo) digital mammography in the detection of abnormalities in the breast, including early breast cancer. Read more about this study

About this study

The primary goal of this study is to compare, within a clinical screening setting, the performance of stereoscopic digital mammography with standard (non-stereo) digital mammography in the detection of abnormalities in the breast, including early breast cancer.

Read the detailed description

The clinical trial, begun in December, 2004, is being conducted at Emory University. Over the next three years, we will enroll and image about 2000 women who are at elevated risk for development of breast cancer (personal or family history of breast cancer) as they come in for their annual screening examinations. Each participating patient will be imaged with both systems, and the stereo and standard (non-stereo) images will be read independently by different mammographers.

A stereoscopic digital mammogram consists of two x-ray images of the breast acquired from slightly different points of view on a digital mammography unit. The x-ray source is rotated 10-degrees between the two exposures while the position of the breast remains fixed in the compression device. The stereo pair of mammograms is viewed on a new third-generation, high-resolution stereo display workstation that was developed in the first part of this project. The mammographer views the stereo display wearing lightweight polarized glasses, enabling him or her to see in depth the internal structure within the breast. As a result, a subtle lesion that may be obscured by superimposed normal tissue in a standard 2D image, now becomes visible as the overlying and underlying normal tissue is separated in depth. Conversely, layers of tissue that may falsely resemble a lesion in a standard 2D image due to chance superimposition, are seen in the stereo mammogram to lie at different depths and, thus, will not be mistaken as a lesion.

We anticipate that with stereo mammography the mammographers will detect subtle lesions in the stereo images that are missed in the non-stereo images. We also expect that there will be fewer false positive detections with the stereo images compared to the standard images. Finally, we also expect that the mammographers will be more confident in their judgments of what they see in the stereo images, resulting in a reduced rate of recall of patients for further work-up.

Questions about this trial

What is this clinical trial studying?

A study testing Stereoscopic Digital Mammography in people with Breast Cancer, run by Emory University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

sensitivity/specificity (time frame: Aug '04 to Dec '07). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00208871, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2013; AzTrials last refreshed its copy on 8 Nov 2026.
