MRI breakthrough could revolutionize diagnosis of common heart problem aortic stenosis

Researchers have developed cutting-edge MRI technology to diagnose a common heart problem more quickly and accurately than ever before. Aortic stenosis is a progressive and potentially fatal condition, affecting about five per cent of 65-year-olds in the US — with increasing prevalence in advancing age. Symptoms include chest pains, a rapid fluttering heartbeat and feeling dizzy, short of breath and fatigued — particularly with activity. The new study reveals how a four-dimensional flow (4D flow) MRI scan can diagnose aortic stenosis more reliably than current ultrasound techniques. The superior accuracy of the new test means doctors can better predict when patients will require surgery.
