RV LGE Assessment. a RV LGE score: RV divided into 9 segments. Each segment graded as follows: 0—no LGE; 1—LGE involving < 1/3 of segment; 2—LGE involving 1/3—2/3 of segment; 3—LGE involving \(>\) 2/3 of segment (maximum possible score 27) b Example of cine ventricular short axis in diastolic phase c Example of LGE imaging in the ventricular short axis. d % RV LGE Extent: Areas of LGE highlighted using semi- automated manual thresholding. % RV LGE Extent = (RV LGE mass/ Total RV mass) × 100
