Background MOLLI [1] uses interleaved Look-Locker (LL) blocks for cardiac T1 mapping. Data is fit to the equation A-Bexp (-TI/T1*) to yield an “apparent” T1 (T1*), which is dependent on both the true T1 and imaging parameters. To estimate true T1, a “LL correction” T1est=(B/A-1) T1* [Eq. 1] has been proposed [1,2]. Although this correction can provide reasonable estimates of true T1, we are not...

In this study, I propose a five-step algorithm for synthetic control method comparative studies. My builds on the model of Abadie et al., 2015 and later Amjad 2018. apply all three methods (robust PCA control, robust control) to answer hypothetical question, what would have been per capita GDP West Germany if it had not reunified with East in 1990? then algorithms two placebo Finally, check rob...
