nitro strength analysis which is done after contrast which is a completely different analysis again you be able to compare namely myocardial infarct of myocardium and then decide whether or not that's a useful comparison finally a third way to analyze it could be the ECG map again comparing two regions by with the addition of hematocrit to determine whether or not this is a useful analysis so three different methods of analysis that you CV map is actually a combination of both t1 map B contrast in force contrast what that means is this is the most difficult analysis to perform because he would need this data as well as this data in order to come up with this data just to give you an example of that these look like and they'll be analyzed so we have this initial map that you can see here this is the delayed enhancement sequence showing you this scar and this patient with mic analysis in a busy level down and there's a study that's done post contrasts or is with fibrosis I will demonstrate the show 31 in relaxation time so if we
