T1 mapping may be a promising technique to quantify myocardial changes in heart failure even when the subject cannot hold their breath. T1 mapping using modified look-locker with saturation recovery in this small swine study shows a quantitative difference in T1 value between healthy baseline and heart failure hearts. The immunochemistry suggests a change in amounts of Type I, III and VI collagen in the myocardium between the control and heart failure swine, but more research needs to be done.
