The analysis of a NH3 study results in a parametric MBF map if this option has been enabled in the modeling configuration. It is calculated in the background if the automatic check is enabled for modeling, otherwise parameteric mapping can be started with the Map button. The map can be shown with the selection illustrated below, and saved using the saving button below Map.
Note that the MBF (NH3) MASK is derived from the model of the left ventricle. In the case of a the centerline definition the mask is obtained by the pixels around the centerlines within the wall thickness. In the case of the epi/endo defintion by the volume enclosed withing the two surfaces.
