Figure 2

Computer simulations showing T2* accuracy, precision and certainty estimates. Top row: Differences in measured and true T2* using echo times from liver and cardiac sequences. Black dots indicate mean error of measured T2*. Red bars indicate confidence intervals (CI). Bottom row: Comparison of estimated CIs (blue and black) and the reference (red) from 2 000 repetitions, which lies within the confidence limits of the estimated CIs.
