Viscoelastic Parameters Estimation and Imaging for the Assessment of Axillary Lymph Nodes


About this study

This study is being done to:

• Test an investigational stiffness measurement and imaging method on the lymph node found in the underarm area.

• Compare investigational imaging to sonography images.

• Compare investigational information to FDA approved US elasticity imaging conducted by SuperSonic Imaging (SSI) machine on the same lymph node in your underarm area.

• Compare to FDA approved ultrasound stiffness imaging system (GE Logiq E9)

• Compare to ultrasound images using Alpinion clinical ultrasound platform, FDA approved ECUBE 12and a non-FAD approved ECUBE 12R

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Female patients who have axillary lymph nodes which may be benign or may have been diagnosed or suspicious for breast cancer will be candidates for enrollment.
  • It is anticipated that the majority of these participants will undergo an US guided lymph node biopsy (standard of care). U.S. and CUSE/SDUV data collection from each participant will take place before or 2 weeks after lymph node biopsy/aspiration.  

Exclusion Criteria: 

  • Having any condition that does not allow proper use of our imaging devices.
