Heart scan showdown: CT vs. MRI for detecting hidden damage

This study is testing whether a CT scan can do the same job as an MRI for looking at heart muscle damage and scarring. MRI is the current gold standard but is slow, expensive, and not suitable for everyone (e.g., people with pacemakers or claustrophobia). The researchers will enroll 2,200 people who already need a heart CT for other reasons and will follow them for years to see if the CT findings can predict future heart problems like heart failure or death.
