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.
Row 1:
Shows a cardiac MRI for subject 201.
Row 2:
Shows a cardiac MRI for subject 202 with a different MRI machine.
