Clare Diagnostic Echo & Research and Vascular Imaging Solutions


We are an Arizona based organization with the ability to offer multi modality ultrasound to clients participating in clinical trials.  As independent research sonographers CDER along with Vascular Imaging Solutions provide the services needed. All studies can be performed in the comfort of our beautiful office located in Surprise, Arizona, the luxury of the clients home, or the research facility.  With our portable equipment we are able to cater to the needs of the study as we will also travel outside of Arizona if requested.  

As an added service, we also provide education, one on one training, and assessment of skill set for sonographers.  We take the time to analyze the competency level of your sonographer as well as provide on-going feedback of progress.  This will ensure your patients are receiving the quality ultrasound along with accurate treatment plan.
