Myocardial fibrosis alters Gd-contrast agent dynamics.
Myocardial partition coefficients calculated from a
multipoint slope calculation will vary in healed
myocardial infarction based on the selection of samples.
This includes the use of pre-contrast measurements and
samples early after contrast agent administration.
Partition coefficient calculations are insensitive to
data sampling effects in viable myocardium.
