Spot Compression Ultrasound Compared to Traditional Breast Ultrasound

July 16, 2026 updated by: Duke University

Efficacy of Spot Compression Ultrasound Compared to Traditional Breast Ultrasound

The purpose of this study is to determine the efficacy of targeted breast ultrasound ("ultrasound in the grid") performed concurrently with diagnostic mammogram during breast compression with an open mammogram paddle in lesion detection when compared to standard diagnostic breast ultrasound. Open paddle spot tomosynthesis and ultrasound in the grid images will be compared to the standard of care, and outcome measures will include comparing accuracy of lesion detection with the new technique versus the standard of care and differences in time to acquire the images for the new technique versus the current standard of care. Radiologists will also review the different sets of images and give confidence scores of lesion correspondence between mammogram and ultrasound. This will be a pilot study of 25 patients to demonstrate proof of concept and is intended to lay the foundation for future funded research with a larger patient population.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Spot Compression Ultrasound
This arm includes all participants enrolled in the study who will receive the experimental imaging technique
Diagnostic test: Targeted ultrasound in the grid
Patients will have a single spot tomosynthesis mammogram image performed with an open compression paddle and concurrent targeted ultrasound imaging of the breast tissue contained in the open mammogram paddle while the breast is in compression.
Other Names:
  • Spot tomosynthesis mammogram

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of breast masses detected
Time Frame: Single visit, up to approximately one hour
The primary outcome will be whether breast masses can be detected using an open mammogram spot tomosynthesis compression paddle and targeted ultrasound in the grid using the experimental technique.
Single visit, up to approximately one hour

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to acquire images
Time Frame: Single visit, up to approximately one hour
The total amount of time to acquire the experimental images (spot tomosynthesis mammogram view with open paddle and targeted ultrasound of breast tissue within the open compression grid).
Single visit, up to approximately one hour
