From: Comparing analysis methods in assessing dynamic dual bolus cardiac magnetic resonance perfusion flow
Mid-ventricular short axis view of the minipig heart with contrast agent inflow. The TurboFLASH sequence was used for imaging. The 6 standardized ROIs from the nuclear medicine 17 segment heart model are shown (cf. text). 2 : Saturated and reconstructed arterial input function (AIF (a)) and tissue response function (TRF (b)). The TRF time series owes much more noise than her AIF counterpart, due to movement of the septum not being compensated for by cardiac gating. 3 : Boxplots of perfusion flow assessed with the eight analysis methods compared to the 8 methods arithmetic mean, respectively the 5 methods arithmetic mean.
