In this study we performed an inter-site, inter-vendor
comparison of myocardial T1 mapping in preparation for a
large multi-centre study. Native myocardial T1
measurements were compared in five healthy volunteers
using different MOLLI variants on two 3T scanners (one
Siemens, one Philips) from different vendors at
different UK centres. Some bias (~2%) was observed
between one variant and the other two, although this
variant was only tested at one site and requires further
validation. Bias between the other variants and the
vendors/sites was small, providing support for the use
of these techniques in multi-centre studies.
