4D Flow
Comprehensive Cardiac Solutions For Complicated Exams
What is it?
•
3D Cine (EFGRE)
•
Capture data in 7 dimensions
•
Valvular Disease
Shunts
3 in space, 1 in time, and 3 in velocity direction
Benefits
•
Non-invasive 3D cardiac anatomy, function, and flow in 1
free-breathing, 8 min scan
•
Unsupervised cardiac imaging – no expertise or clinician
guidance needed
•
Faster cardiac exams help to shorten backlog scheduling
times
•
Cloud-based or on-premise visualization and reporting
attracts new referrals
