Feasibility of Comparing Microwave Images to Clinical Information in Patients Recalled for Follow-up Breast Imaging

Enrolling by invitation · Not applicable

Conditions studied: Breast - Female

In brief

The goal of this clinical trial is to measure the electrical properties of breast tissues using microwave technology and to compare these collected measurements to clinical information in mammograms and/or breast ultrasound for women that have been recalled for follow-up breast imaging or further investigation. The main questions it aims to answer are: 1. Can the breast area and plate separation in the microwave scan be compared to mammogram data (where available) to assess similarity in breast positioning and the feasibility of image registration? 2. Can the distribution of electrical properties specifically glandular tissue distribution in the microwave image be compared to that observed in the mammogram (where available)? 3. Can the characteristics of the microwave image in the localized region corresponding to an identified anomaly in the breast imaging data be examined? Study participants will be scanned with the Wave View microwave scanner on the same day as their follow-up breast imaging appointment. Each breast will be scanned up to 3 times with the scanner oriented in both the horizontal position and oriented at 45 degrees. Study participants will also be asked to fill out three surveys, one relating to breast health and the other two relating to their scanning experience.
