Figure 1From: Longitudinal stability of gel T1 MRI Phantoms for quality assurance of T1 mappingshowing longitudinal trend for T1 maps and ECV. All T1 parameters remained relatively stable, with native myocardium remaining the most stable. This is particularly useful for T1 mapping sequences only utilizing native myocardial values. The ECV also remained relatively stable during these 52 weeks, suggesting that gel phantoms can be accurately used in the quality assurance of T1 mapping.Back to article page
