Video Transcription

Video Summary

The transcript covered a cardiac MRI teaching session on parametric mapping and cardiomyopathies.<br /><br />First, Vanessa explained parametric mapping as the “fourth era” of CMR after cine imaging, late gadolinium enhancement, and stress perfusion. She reviewed T1, T2, and extracellular volume (ECV) mapping, emphasizing their quantitative, reproducible nature and their value in detecting edema, inflammation, fibrosis, iron overload, amyloidosis, Fabry disease, and different hypertrophy phenotypes. T1 and T2 values rise with water content, while iron lowers both T1 and T2*. ECV requires pre- and post-contrast T1 plus hematocrit and is a marker of interstitial expansion. She stressed that mapping is powerful but nonspecific and must be interpreted in clinical context.<br /><br />Next, Chiara Bucciarelli-Ducci discussed CMR in MINOCA and INOCA. She explained that MINOCA should be treated as a working diagnosis, not a final one, and that CMR often reveals the true cause: myocarditis, Takotsubo, or small infarction. She also covered acute coronary syndrome imaging, including myocardial edema, infarct size, microvascular obstruction, hemorrhage, and myocardial salvage. In INOCA, she highlighted quantitative perfusion CMR for detecting epicardial and microvascular ischemia.<br /><br />Odrona then reviewed left ventricular hypertrophy, focusing on hypertensive heart disease versus athlete’s heart. She described how CMR helps assess wall thickness, LV mass, chamber size, and fibrosis, with clinical context being essential for differentiation.<br /><br />Paulus presented hypertrophic cardiomyopathy, including diagnostic thresholds, common morphologic patterns, LVOT obstruction, apical aneurysms, fibrosis, and CMR’s role in risk stratification and phenocopy detection.<br /><br />Finally, Justyna covered dilated cardiomyopathy and arrhythmogenic cardiomyopathy, detailing diagnostic criteria, CMR protocols, tissue characterization, and examples showing how CMR helps identify etiology and guide management.
