Background Extracellular volume fraction (ECV) calculation requires myocardial and blood T1 measurements to be acquired preand post-contrast administration. T1 star (T1*) may offer a more accurate estimation of blood pool T1 as it avoids look-locker correction, and so is theoretically a more robust measure of blood T1 where fresh spins are flowing into the image plane. Reproducibility of blood ...

When two targets (T1 & T2) are presented in rapidsuccession, observers often fail to report T2 if they attendto T1. The bottleneck theory proposes that this attentionalblink (AB) is due to T1 occupying a slow processing stagewhen T2 is presented. Accordingly, if increasing T1difficulty increases T1 processing time, this should cause agreater AB. The attention capture...

Pixel-by-pixel calculation of T1 values (T1 mapping) has been used in different tissues to focus on T1 changes in a quantitative fashion. The aim of this study was to establish T1 mapping of human myocardium on a 1.5 Tesla system and to examine its diagnostic potential in patients with acute myocardial infarction (AMI). 8 patients with reperfused AMI (day 3 ^ 1) underwent multi-breath-hold MRI ...
