Uncertainty analysis for error propagation in five
semi-quantitative DCE-MRI parameters was performed. Five patients with NF2
were used for evaluation. Percent deviation
(PD) distributions from Monte Carlo simulation were compared with in vivo
data. Results: 1) The sum of SE and SErel had greater precision than
non-summed metrics for persistent type SI(t); (2) The normalized parameters
had poorer precision than non-normalized metrics;(3) Rse1/se2 was more
accurate for persistent type than
washout type; (4) Rse1/se2, showed
wide PD distribution. In
