The signal acquisition number is related to the
computational complexity during signal analysis in MR
fingerprinting. In this study, we develop a contour area
index and demonstrate a quantitative method to evaluate
the mapping precision under different signal acquisition
numbers. It has potential in evaluating different RF
excitation schemes in MR fingerprinting.
