T1 mapping performance and measurement repeatability: results from the multi-national T1 mapping standardization phantom program (T1MES)

Abstract

The T 1 Mapping and Extracellular volume (ECV) Standardization (T1MES) program explored T 1 mapping quality assurance using a purpose-developed phantom with Food and Drug Administration (FDA) and Conformit Europenne (CE) regulatory clearance. We report T 1 measurement repeatability across centers describing sequence, magnet, and vendor performance.
