Quantitative magnetization transfer (qMT) requires
several additional measurements to correct for
instrumental biases (B
to constrain parameters in the fitting model (T
When using variable flip angle (VFA) T
used twice before fitting the qMT parameters: to correct
, and the MT saturation powers.
Inaccuracies in B
propagate to the fitting of the qMT parameters through
two pathways through errors in T
MT saturation powers. This work demonstrates that for
the Sled and Pike qMT model, certain qMT parameters (F,
) are insensitive to a large range of B
when using VFA.
