Foundations of CMR: Level 1 Virtual Course-SESSION 6: CMR: OTHER INDICATIONS

Video Transcription

Video Summary

The transcript covers a cardiac MRI educational session with several expert talks. Dr. Amit Patel discussed stress CMR for ischemia, explaining standard perfusion protocols, quantification of myocardial blood flow, and how techniques like dual bolus, dual sequence, and inline mapping improve interpretation. He emphasized that quantitative perfusion helps detect epicardial coronary disease, multivessel ischemia, peri-infarct ischemia, and coronary microvascular dysfunction, and may also support contrast-free approaches using BOLD imaging and breath-hold maneuvers.<br /><br />Dr. Manish Motwani then presented a structured approach to cardiac masses. He categorized masses into pseudotumors, secondary tumors, and primary tumors, stressing the importance of location, size, mobility, tissue characterization, contrast behavior, and extracardiac extension. He reviewed classic MRI patterns for lipoma, myxoma, fibroma, thrombus, angiosarcoma, lymphoma, metastases, and pericardial cysts, showing how a standardized MRI protocol can narrow the differential and guide management.<br /><br />Dr. Karen Ordovas focused on pericardial disease. She explained MRI findings in constrictive pericarditis, acute and chronic pericarditis, complex effusions, and pericardial tumors. She highlighted septal bounce, pericardial thickening, enhancement, tagging for constriction, and the role of MRI in distinguishing benign cysts and lipomas from malignant pericardial invasion.<br /><br />Finally, Dr. Aparna Airodi reviewed MRI and MRA in Takayasu arteritis. She described how MRI helps diagnose disease, map vascular involvement, assess wall thickening and enhancement, and monitor activity without radiation. She also discussed the “double ring” sign, type-based classification, and the challenges of determining true inflammatory activity versus fibrosis. The session ended with a wide-ranging Q&A on perfusion, masses, pericardial imaging, and vasculitis.
