We have developed a new method for determining the
optimal TI value, called Polarity-Corrected (PC) TI Prep
tool, based on the IR + 2D segmented FE technique. In
this new method, the acquired data is corrected to match
the data points after magnetization recovery by phase
correction, and curve fitting with RR correction is then
applied to determine the optimal TI value analytically.
This method can also be used to measure the T1 values
together with the optimal TI value, which suggests that
it should be suitable for use as a T1 mapping tool in
commercially available MRI scanners.
