We measured and compared the transcytolemmal cellular
water exchange rates of fibrotic and viable myocardium
in patients with chronic myocardial infarcts.
Transcytolemmal water exchange rates differed between
infarcted and viable myocardium. Viable myocardium can
be assumed to be in fast exchange limit. Infarcted
myocardium has significantly slower exchange which
alters the linearity of contrast curve shapes.
