Bias and SNR of T(1) estimates derived from joint fitting of actual flip-angle and FLASH imaging data with variable flip angles
Previous work has suggested fitting joint AFI/FLASH data for T1 and B1+ by minimizing the 2-norm of the difference between the signal model and measurements will produce unbiased estimates of T1. We demonstrate that, contrary to previous results, the estimator has a substantial bias that varies with...
