For LGE - Late Gadiolium Enhancement, it is dealing with the timing of the reading. Often it is either present or not present. If present, they may look at presence per segment (even provide the percentage of the presence per segment).
The image is read 8-10 minutes after the contrast is given.
Determined this would be an indicator test and there is an additional term LGE percentage.
Is "CARDIAC WALL" okay for location?
It is the only term in CT that fits. It seems wrong because technically if there is a mass within the heart, it would be seen on the CMR imaging.
All the segments in the CT is for the LV, is it safe to assume the same segments for RV?
Row 1:
Shows a cardiac MRI for subject 201.
Row 2:
Shows a cardiac MRI for subject 202 with a different MRI machine.
