MRI scans of blood vessel turbulence need better calibration, researchers warn

A technical letter challenges how hospitals measure turbulent blood flow using MRI imaging, pointing out that scanner settings and vessel size significantly affect results. The finding matters for cardiology clinics and medical device makers relying on these measurements to diagnose stroke risk and heart disease.
