Healthy Clinical Trial
Official title:
Measuring Electrical Properties of Breast Tissues
The goal of this observational study is to use a low-powered microwave imaging system to provide insight into the correlation of electrical properties of breast tissue at microwave frequencies and breast density obtained from mammograms in healthy women between the ages of 18 and 74. The main questions it aims to answer : • Is there a correlation between the electrical properties of breast tissue and breast density obtained from mammograms? Both breasts of each participant will be scanned by the microwave imaging system six times in total.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Measurement of electrical properties of breast tissue | The electrical properties will be estimated for each volunteer and an image that maps these properties will be created. | 18 months | |
Secondary | Correlation between the electrical properties of breast tissue and breast density | Comparison of the microwave images and mammograms in 2 ways: VOLPARA scores versus average electrical properties and comparison of regions of interest in both images | 18 months |
