Select myocardial frames during upslope (top row) and their corresponding pixel-wise contrast enhancement ratio (CER) maps. Note that the SNR and CNR of original frames permits automatic contouring that, along with registration, can facilitate image analysis. In this case, the contours were drawn automatically in the first frame, and were then propagated to other frames. Also note that bloodpool signal remains almost constant with changing [Gd] and is therefore suppressed in CER map.
