Parametric Mapping: Normal Values, Standardization, and Implementation

Video Transcription

Video Summary

The talk explains how to standardize and quality-assure T1 mapping in cardiac MRI. It distinguishes site-specific normal values from true reference ranges, stresses healthy volunteer recruitment, normality testing, outlier removal, and publishing local values. It reviews phantom-based standardization using HCMR, TIMES, and NIST phantoms, plus Z-scores, multicenter QA, and software harmonization. It highlights protocol checks with B0 field maps, repeatability thresholds, and training analysts to reduce variability. Practical tips include choosing phantom tubes by disease type, checking for phantom damage, and using standard deviation maps to judge whether T1 differences are real.
