In an intra-individual, interventional, parametric, cardiac MRI study, T1 and T2 relaxation times were reduced compared to baseline after dehydration indicating a detectable effect of the hydration status on relaxation time assessment.

Figure 1. Colum graphs show differences for T1 (A) and T2 relaxation times (B) in healthy volunteers on baseline, after 12 hours of fasting (“dehydration”) and after rehydration (“hydration”). Data are presented as mean with 95% confidence interval error bars.
