Extracellular volume fraction (ECV) of the myocardium
can provide a quantitative measure for cardiomyopathies.
In our research we propose the use of a free breathing
T1-mapping method combined with dedicated post
processing to acquire whole heart ECV maps based on
native and post contrast T1-maps. We compared this
method to the MOLLI T1-mapping method, and found a
non-significant bias towards higher ECV for our method.
The proposed method facilitates whole heart ECV mapping
in the same amount of time as MOLLI, however it
circumvents the need for multiple breath holds, making
it more suitable for patients.
