Technologist Track Session 2: CMR Myocardial Delayed Enhancement (2019)-Bright Blood Delayed Enhancement

Bright Blood Delayed Enhancement

Video Transcription

Video Summary

Cardiac MRI is highly useful for distinguishing heart diseases by their characteristic scar patterns. It can confirm myocarditis, sarcoidosis, amyloidosis, and hypertrophic cardiomyopathy, and guide biopsy to affected tissue. The speaker emphasizes MRI’s value in non-ST elevation MI: catheterization can miss the true infarct-related artery, especially with nonobstructive or multivessel disease. MRI can reveal hidden infarcts, identify the culprit vessel, and detect patients mislabeled as myocarditis or normal coronaries. Overall, CMR improves diagnosis, risk prediction, and treatment decisions in complex cardiac cases.
