Abstract
Background The choice of post contrast acquisition time is crucial to optimize T1 mapping. Indeed, equilibrium is required for a reliable characterization of interstitial myocardial fibrosis. The majority of studies regarding T1 equilibrium were performed on healthy subjects. Accordingly, the aims of our study were 1) to assess post-contrast T1 Kinetics in HCM patients, in comparison to healthy volunteers, and 2) to determine acquisition times that enable a better differentiation between the two groups.

The choice of post contrast acquisition time is crucial to optimize T1 mapping
The aims of our study were 1) to assess post-contrast T1 Kinetics in HCM patients, in comparison to healthy volunteers, and 2) to determine acquisition times that enable a better differentiation between the two groups
We studies 14 HCM patients (10 males, age:58±12 years, myocardial wall thickness=12±4 mm, Heart rate=61±9 bpm), diagnosed by echocardiography, and 9 healthy volunteers (4 males, age:33±16 years, myocardial wall thickness=5±1 mm, Heart rate=71±10 bpm)
