Although it has been slow to catch on, the use of magnetic resonance imaging (MRI) to visualize heart function may soon be the preferred option. This is because not only can an MRI diagnose disease, but it can also help predict the severity of each case.
In a study from Duke Health, researchers found that MRI has the potential to be a non-invasive, non-toxic alternative to stress electrocardiograms EKGs, cardiac catheterizations and stress nuclear exams in identifying the severity of a patient’s heart disease.
This technology was previously unpopular for this particular use because of a lack of data on its predictive value. Also because it is not possible for those with pacemakers to receive MRI testing because it can harm the patent. Researchers note that the study provides some clarity but that direct comparisons between diagnostic tests should be conducted.
