From: The relationship between spatial resolution levels and quantitative myocardial perfusion
Bars are representing mean and standard deviation of FRI at different level of spatial resolution. Figures (a) and (b) correspond to reduction of the resolution in transmural direction and angular direction, respectively. Mean FRI value has increased as resolution falls down for all methods. This is more obvious for ARMA and exponential methods and transmural direction averaging. STD has increased as resolution falls down for all methods.
