Multi-Dimensional Parametric Mapping

Video Transcription

Video Summary

The talk explains why multidimensional parametric mapping in cardiac MRI is valuable: it produces quantitative T1/T2 maps that better detect diffuse myocardial disease. Traditional methods fight cardiac and respiratory motion with ECG triggering and breath-holds, leading to long, complex exams and misregistration. Multidimensional mapping instead embraces motion by sorting data into multiple time dimensions, enabling single-scan, free-breathing, and potentially ECG-free imaging. The speaker reviews key approaches such as XD-GRASP, MR multitasking, low-rank tensor methods, and MR fingerprinting, highlighting their ability to generate co-registered motion-resolved parameter maps and improve future clinical cardiac MRI workflows.
