New MRI scan could replace invasive heart test for lung pressure patients

This study looked at whether a special MRI scan (4D Flow) can accurately measure blood flow to the lungs in people with both congenital heart disease and pulmonary hypertension. The standard test for this is a heart catheterization, which is invasive and uncomfortable. The study involved 50 patients aged 7 and older. Researchers compared the MRI results to the catheterization results to see if the MRI could be a reliable, non-invasive alternative for monitoring these patients.
