Trial Summary

What is the purpose of this trial?

This trial is testing a new device designed to help screen for and diagnose breast cancer. It targets individuals who are undergoing breast cancer screening and diagnosis. The device works by scanning breast tissue to identify any unusual changes or lumps that could indicate cancer.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is the IzoView Breast CT Imaging System safe for humans?

The breast CT system, including the IzoView, has been tested on 55 women, including healthy volunteers and those with a high likelihood of breast cancer, using radiation doses similar to standard mammography. Initial results show promising imaging quality, and the system is undergoing further safety and performance evaluations. ^{1 2 3 4 5}

How is the IzoView Breast CT Imaging System different from other breast cancer screening treatments?

The IzoView Breast CT Imaging System is unique because it uses a dedicated computed tomography (CT) system to scan the breast in a pendant position, providing detailed 3D images without compressing the breast, unlike traditional mammography. This method offers excellent anatomical detail and visualization of soft tissue and microcalcifications, potentially improving the detection of breast cancer, especially in dense breast tissue. ^{2 3 4 6 7}

What data supports the effectiveness of the IzoView Breast CT Imaging System treatment for breast cancer screening?

Research on breast CT systems shows promising results, with excellent anatomical detail and good visualization of tumors, similar to the IzoView system. Initial studies indicate that breast CT can effectively enhance tumor visualization, especially with iodine contrast, suggesting it may play a role in breast cancer imaging. ^{1 2 4 8 9}

Eligibility Criteria

This trial is for women at least 35 years old who need a mammogram or breast biopsy, regardless of race and ethnicity. It's not for those who may be pregnant, cannot stand independently due to being wheelchair-bound, have breast implants, pacemakers, or IV ports in the area where the mammogram takes pictures, or have been in this study before.

Findings from Research

Breast CT imaging, utilizing advanced cone beam technology, is being developed as a promising alternative to traditional mammography, particularly due to its ability to reduce imaging artifacts and improve image quality.

A new prototype system for breast CT is being designed for image-guided interventional procedures, with plans for a multi-institutional clinical trial to evaluate its effectiveness in breast imaging.

New mammography technologies, particularly breast tomosynthesis, have been shown to increase breast cancer detection rates while reducing the number of unnecessary biopsies, making it a promising advancement in breast cancer screening.

Breast tomosynthesis is currently the only 3D mammography technique in clinical practice, and its FDA-approved protocol involves more imaging projections, which increases the associated risks of radiation exposure compared to traditional 2D mammography.

Screening mammography has significantly reduced breast cancer mortality by 41% since 1990 in the U.S., supported by various studies and advancements in therapy.

Digital breast tomosynthesis enhances the accuracy of mammography by improving sensitivity and specificity, making it particularly beneficial for patients with overlapping breast tissue.
