In a high-volume tertiary cardiac center, our goal is to deliver high-quality, accurate imaging reports within a reasonable turn-around time. Circle Cardiovascular Imaging provides seamless image post processing solutions across different scanning platforms for our fellows and consultants. Our partnership with Circle extends beyond the clinical service and CMR training. cvi42 is the selected application to support the many research studies managed by our CMR Research Core Facility.

I have worked with Circle Cardiovascular Imaging for almost ten years - initially for research only. Because of its speed, accuracy and optimized workflows, we have been using it clinically for about four years now. Without cvi42 and report42 we would not be able to deliver our high volume CMR service with over 12 consultants and many more trainees. But what is best about Circle is the customer service and the drive for continuous improvements and innovation.

We have been using cvi42 since the beta version of the product in 2008 and it has shaped the way we work in CMR. Despite many innovative and technological advancements over the last decade, the software kept its core simplicity that allows for a productive workflow. We are confident that cvi42 will continue to carry on its’ cutting edge reputation and deliver more value in our CMR exams.

As soon as you use Circle’s software, you’ll notice the completeness of the tools. The software is comprehensive for simple, routine studies as well as for advanced, more complex research purposes. The multi-vendor and “pathology tagging” capabilities help enhance presentations, education, workshops and multi-centric reviewing of studies. The report tool is simple and allows a faster read time per patient. Circle’s strongest asset, however, is their great customer support - they have become the reference for CMR imaging today.
